Aluminium battery gimmick or do you want

Today, a professor at Hunan University developed an aluminum ion News appears in the media.

In its report, said Professor at Hunan University published in the renowned scientific journal papers, developed a fast charge, long cycle life of aluminum ion batteries, will change the world. The funny thing is, on the same day, there is a news that United States Stanford University also developed an aluminum ion batteries, fast-charging long life, what's going on here? Who on earth do? Did this thing fly? Can really change the world?.

Who on earth do?

China News: top international online academic journal nature published the physics and microelectronics Sciences Associate Professor Lu Bingan, who as the "first author" dissertation rapid charging and discharging of aluminium battery. Believe the study results in the journal nature, batteries rechargeable aluminum ionic liquids for the first time, this could revolutionise international battery industry.

Lu Bingan said, using lithium-ion batteries in the past charging of the phone takes 1 hour to complete, aluminum battery takes only 1 minute to complete. From now on, aluminum battery charge 1 hour phone uses 3, 4 days is no longer hypothetical.

Chinese Professor in Stanford's information is HongjieDai and his colleagues of the innovative aluminum ion battery research is published in the April 6 issue of the natural sciences.

Aluminium cell consists of two electrodes: "a negatively charged anode made of aluminum and a positively charged cathode, people have tried different materials for the cathode," Stanford's team unexpectedly discovered a simple solution to this problem is to use graphite, graphite is essentially carbon. Some types of graphite materials can produce very good features. "Battery installation for the Stanford research team will study the aluminium anode and graphite cathode and salt electrolyte is liquid at room temperature, so it's very safe. Our aluminium rechargeable batteries can produce 2 volts. Than any aluminum battery can produce a higher voltage. "But our typical lithium battery only reaches half the battery voltage, if improvements should eventually increase the voltage and energy density cathode materials. So, we created the battery will meet all you thought battery features: inexpensive electrodes, secure, high-speed, flexible charging and longer life expectancy. I've seen the new prototype of the battery, which is really exciting. "The inventor said.

Other researchers include this study from Taiwan Industrial Technology Research Institute's visiting scientist Lin Mengchang (Meng-ChangLin), Lu Bingan Hunan University (BinganLu) and Wu Yingpeng postdoctoral scholars (YingpengWu). Other authors include Stanford University, the King deferred (Di-YanWang), Guan Mingyun (MingyunGuan), maikeer·anjier (MichaelAngell), Chen Changxin (ChangxinChen) and Jiang Yang (JiangYang); and the Taiwan National Normal University, Huang Bing Joe (Bing-JoeHwang). This study was supported by the United States of energy, Taiwan Industrial Technology Research Institute, Stanford University's global climate and energy project, Stanford puleikete Energy Research Institute and the Taiwan Ministry of education support.

Comparing two reports, we can see that the project is United States agencies such as the Department of comprehensive research project providing resources, Hunan University Professor Lu is just one of the researchers. This is a United States research project instead of Hunan University, the domestic transmission is suspected of heading the party.

Al-Ionic battery technology breakthrough in? X-DORIA iWatch Case

Aluminum batteries have long been thought to have some promising research, because of its great potential for energy density. But so far, aluminium battery has only been used as metallic fuel cell, not charging, but change the aluminum electrode to make up. A while ago what hundreds of kilometers of aluminium cell vehicles say is this thing.

Aluminum battery not charging battery poor cycle life on the one hand, on the one hand is charging too slow, not practical. There's a fatal flaw is the electrolyte inside the aluminum ion instability and pose a danger are prone to chemical reactions. These weaknesses make aluminum battery has no practical use.

From the perspective of information papers, Stanford this project has developed a special graphite anode material, to charge quickly. News did not explicitly said to be Graphene, Graphene materials for the past few years there have been many negative news to improve lithium battery charging, Spain has even done loading tests at a university level.

However, most of the graphite negative electrode life cycle is very short, Stanford the 7,500 times do not decay is a miracle. If the data is true, that have made breakthroughs in materials. In addition, Stanford has found a suitable electrolyte ensures battery safety, Dr if not lying, this battery security than a lithium-ion battery, which is very rare. Therefore, the aluminum ion battery actually progress in the material, the new cathode and electrolyte in the new performance ideal for aluminium ions battery was manufactured.

How far is it from practical?

It has come to our attention, also says the battery is the prototype of the inventor, rather than a finished product, and this shows that there are many problems. Aluminium batteries had a theoretical capacity is very high, but inventor said to further increase the energy density, suggesting that Guinea pigs at least lack of energy density, and battery power density of aluminum is bad, the voltage is not high, which limits its use. Cycle times is gratifying, charging speed is gratifying, but power is poor, poor power, a lot of places won't take. For example batteries require high volume phone.

But in electric vehicles, especially on electric buses, long-life rechargeable battery is very promising. In addition to technical issues, from laboratory to production processes take a long line how to establish quality control, material consistency have to be resolved.

As inventor said, now have a good shape, may have developed the ideal battery. Al-much cheaper than lithium, graphite is not expensive, as long as the aluminum ion battery energy density, lithium-ion battery power density indicators such as tying, other technical indicators of advantages and costs will entirely replace lithium-ion batteries. Then our world would be changed.

At present, aluminium-ion batteries are only gimmicks, which it hopes will be the new energy.

Samsung may refuse to give up hope to push high end Tizen mobile phone

　　Phone and Tablet operating system was Apple and Google in the world, Samsung always wanted to compete with Apple, Google market, however, Samsung life has failed to insert a foot. YSL iPhone 5 Case

　　However, the smart watch platform, Samsung Tizen operating system still won some presence. Samsung introduced a variety of carrying Tizen operating system smart watches, including the latest release of Gear S2. Thanks to the watch system is emerging, Watch OS and Android Wear are not gaining a foothold.

　　However, Samsung seems to have been the mobile systems market to heart, always wanted to be in on this market to make a difference.

　　According to foreign media reports, Samsung Tizen platform power, is working on a high-end model. Before Samsung used to publish some low-end mobile phones carrying Tizen operating system, such as Samsung Z3, Z1 and Samsung, hope at the low end of a foothold.

　　Both Tizen phone sales is far from satisfactory, especially compared to the Samsung Galaxy series high-end machines powered by Android.

　　Perhaps it is because the policy did not succeed, Samsung will blame cell phones is not high enough, so plan to release high-end Tizen system mobile. YSL iPhone 5 Case

　　Samsung today, as the world's largest mobile phone manufacturer, with the Android operating system is inseparable from the contribution, flagship models such as Galaxy S6 and Galaxy phones rely on powered by Android system such as Note 5 has been successful.

　　Judging from the current situation, Samsung is unlikely to directly for next year's Galaxy S7 or Galaxy Tizen Note 6 carrying system. Therefore, users who also want to purchase Samsung's high-end An Zhuoji can rest assured.

　　If it's not Galaxy S7 or Note 6, then most likely the Z3 's successor. Some analysts believe that, in accordance with Samsung's naming conventions, and Samsung high-end Tizen models may be named or Samsung for Samsung Z5 Z8. Of course, nor does it preclude Samsung launched a new range of possibilities.

　　Samsung Tizen input input of energy as much as Microsoft's Windows Mobile, to promote the development of Tizen system, Samsung and even allowed Tizen platform developers before the end of next year to keep all revenue generated, which sounds like a very attractive conditions, but applications sales could also be a problem. Not too bad Microsoft, Microsoft had released a project called Project Astoria, through this project, developers can directly submit existing Apk application installation package to the Windows Store, Microsoft compiled Android application to Windows application. However, the projects was stranded. Operating system path as difficult as to Samsung and Microsoft.

　　Some analysts believe, Tizen attractive to new and old customers were not enough, the existing Android users hard to Tizen, it is difficult to attract users who had just entered the smart phone market. In addition, Android has fixed market, many manufacturers offer many choices to consumers. If a user from my Android to Tizen system, while cell phones look similar to the Android phone, but less applications and services, users will not like it.

2 g what is buried in China

"Introduction to" 4G the advent of mobile Internet has entered a new era, but the 4G is not as mature as we expected. China currently has commercial 4G technology, 4G walk do not allow voice service channel for the time being. In order to solve this problem, 4G now uses two solutions to this problem, namely the dual standby programme and CSFB, the future, VoLTE is LTE and 4G matches the Internet voice technology.

4G times of comes let mobile Internet of speed into has a new of times, for many young user for, mobile Internet has fast into has phone most important of function, but for many people for, may mobile Internet surf for is not most important of that items function, they still need stable of calls function, so 4G phone now in voice calls function aspects and do of how does, 4G currently and no we imagine of so mature.

For the time being, whether it is TD-LTE or FDD-LTE, above 90% is the same technique used in the field, are a branch of the LTE technology. But China's commercial 4G technology, 4G walk do not allow voice service channel for the time being, so in order to deal with this situation, 4G now uses two solutions to this problem, namely the dual standby programme and CSFB (circuit to fall). Michael Kors Note 4 Cases Michael Kors case for Note 4

Dual standby programme

Double standby programme actually is good understanding, is 4G network and 2/3G network while standby, voice business of when enabled 2/3G network channel, and Internet of when using 4G network, but double standby programme will displayed two a signal, but and not dual SIM double stay, may will on user caused must of confused, and two a network while standby also will has increased power, reduced phone range of problem.

CSFB technology

CSFB (circuit down) is another solution, is used in the Internet 4G network for high-speed Internet surfing, and then call on the phone back to the 2/3G network, then go back to the 4GLTE network. Benefits do not appear like dual standby dual signal and increase the power, the disadvantage is that down there is a delay, and if the user data when voice calls, data service will fall back to the 2/3G channel.

VoLTE technology

Third is the focus of today, Monogram distribution technologies--VoLTE technologies in the future. VoLTE IP solution is based on the IMS network are LTE voice target programme, final selection of the LTE operators, LTE IMS with the implementation of end-to-end packet-based voice and video communications services and supplementary services with circuit performance. SRVCC (SingleRADIoVoiceCallContinuity) is a VoLTE a supplementary technology of the times, it solves the Terminal from LTE network to LTE network coverage-free (3G/2G cover) place, single radio frequency terminals controlled by the IMS VoIP voice and seamless switching between CS voice.

Simply put, VoLTE is LTE and 4G matches the Internet voice technology.

With the growing maturity of LTE network technology, VoLTE is the inevitable trend in the development of LTE voice, but is limited by the VoLTE Terminal products and network devices not mature enough and the current state of the situation, the existing 4G to support and VoLTE system upgrade is needed, such as in the WindowsPhone8.1Update1 increase the support for the VoLTE.

The evolution of technology will be very long, but recently the three carriers is not a hard time, and facing a very complex situation. Whatever the reason, Unicom majored in 3G, main 4G location and telecommunications Telecom no longer have any hesitation in strategy, and through his foresight a year ahead of release, was later the policy space.

Today, China Telecom announced VoLTE-2015 commercial time, technical testing and validation of the technical specification and programming in 2016, a massive network, chips, terminals, network, service, interconnection and IT tests the FBI; the end of 2017, achieve commercial. Includes VoLTE+VoWiFi, HD voice, RCS, VoLTE international roaming. VoLTE compared 2G3G voice calls, sound quality and 40% can also bring lower access delay (waiting time after dialing), 3G drop 50%, probably in about 2 seconds. VoLTE dropped close to zero. The key is, a VoLTE, telecommunication can abandon CDMA standard, solve once and for all "in telecommunications as deep as the sea from this phone is bad" situation ... ...

On the VoLTE, a lot of people don't realize is, after mature 4G full coverage and VoLTE, market introduction of single 4G model Terminal, with three series of 2/3G high against the original chip terminals in the channel to promote the hit, which led to the disruptive impact on operator market. At this point, moving, telecommunications see very clearly.

Of course, if you do not take into account technological evolution and the revolutionary impact of open Terminal market, China Unicom now, because his voice fell itself is no problem, he 3G the Internet itself can be the perfect Voice over IP calls. On the last couple of years, no doubt technically Internet access and call the perfect experience of China Unicom. For advice on how to choose and that is why I 4G shoes says:

Best 3G+ top 4G= perfect experience!

Then, after mature 4G full coverage and VoLTE, market introduction of single 4G model Terminal, with three series of 2/3G high against the original chip terminals in the channel to promote the hit, which led to the disruptive impact on the operators market, Unicom what really want to think about the future?

Netizens gives the answer: If Telecom FDD obtained licence to sell 50 billion moves, estimated mobile certainly happy, right? After mixed network can be realized. And telecommunications and China Unicom cooperation, pooling resources to build a boutique FDD/TD-LTE mixed network, voLTE as soon as possible so that the two outstanding 4G, can save resources, but also for competitive, but also complementary and backup, network security, benefits, think about it drunk ... ...

From PayPal Ant gold suit why independent publishing APP

On August 18, the ants Ant gold service rollout of mobile money platform treasure. This is PayPal in addition to ants take first Gold release new Standalone APP.

Bao and treasures, in addition to the balance shift to the ants gather treasure, new APP has a variety of fund management, to provide users with a-shares and Hong Kong equities, stocks and other financial information.

According to appannie statistics, in the AppStore's ranking, August 18 financial class ranked 8th, China ranked 108; 19th economics ranked 5th, China ranked 77, is a rising trend. Born with a Golden Spoon, there are huge resource advantage, rich Ant jubao trend better than the general business finance APP.

Ant-gold service why will split money from PayPal, an independent APP? I think there are two reasons:

1, from logic, with Tencent would like to heap all businesses are micro-believe it or not, like PayPal take a diverging path.

In the letter "I" in the purse under the Tab bar, there are 20 functions, equivalent of PayPal payments, utilities, movie tickets, O2O and financial functions.

Micro letter has become more and more enormous, on my phone, in addition to photographs, micro application has been the largest in memory, full 3 g.

There is no indication, micro-letters to cut out some of the functions, on the contrary, more Tencent in breaking head wanted to squeeze in. Bloated app beyond Zhang Xiaolong and even Ma's control, but the show was a black hole devouring all desires.

Ant Super APP PayPal although not as micro-gold suit, but still in the TOP5, why do ants follow a streaming user, APP matrix mode?

Ant-gold suit wealth business group President Yuan Leiming's argument is that businesses are concentrated in a single APP makes the APP very heavy, much worse user interference. Product Director Liu Lejun think ants gather treasure, payments and financial markets, it's hard to hit all the points with a product, because there are so many competitors, using a portfolio approach to distributed competition.

Funny thing is, Liu Lejun was product manager for micro, Micro-product manager, large flow of black holes, or triage-type APP matrix is more representative of the future?

2, from the concrete business, Ant gold clothing launch Ant jubao products filter is user, made "firewall" and reduce systemic risk and moral hazard.

Alipay's birth is based on the Department's Internet payment, pay was born around utilities, airline tickets, mobile payment, birth balance treasure until 2013, 2014 development moves treasure.

Treasure if balances are mass products, treasures a certain threshold. Treasures of complex product systems, especially after liquidation functions of doping, it includes targeted financing tools, universal insurance, bonds, and so on. After the liquidation took a personal loan, coupled with guarantees and insurance, ordinary investors and cannot understand the complex relationships.

PayPal using PayPal the most basic population is client-oriented, ability to identify and undertake the risk these people are weak, whether balance treasure or treasure, in addition to commercial guarantees, there are ants gold suits, credit.

Yuan Leiming said Treasury has exceeded 260 billion scale, so far none of the cases payment risk, plus the balance of treasure, both close to 900 billion, to ensure that such funds are not a problem, is very difficult.

If Ant gold clothes using PayPal to get involved in securities trading, bring turbulent users at the same time, also caused a lot of trouble, stocks likely will lose money too much, but the little white users are stock losses blamed on the PayPal reputation--it has great possibilities, increasing divorce rates also can be found in micro-letter.

Similarly, the various stocks, index funds and other riskier products, is unable to drop PayPal client sales, platform hidden reveals costs are too high, Ant-gold service cannot let PayPal take the risk, Ant jubao split screen after the user, leaving the real risk tolerance of investors, reducing the moral hazard of his.

Some think that Ant to get the treasure, it is in response to the Central Bank, born on the new rules on third-party payment, this is not true.

Draft provisions individual comprehensive payment account, where all pay account balance payment should be no more than 200,000 years; personal consumption account, where all pay monthly payment transactions on the accounts of years shall be not more than 100,000 yuan.

Treasure of ants in order to circumvent the account transaction limit?

Third party payment draft released in late July, Ant even the Organization overcome immediately, according to Apple's audit rules, bug-free on line AppStore is almost impossible.

Yuan Leiming revealed that Ant treasure from the Lantern Festival this year has started, internal code name "dumpling", Ant-gold suit all high risk money cut from the payment instrument ideas.

Ants in early July gold had an inkling when the Service announced the new strategy, PayPal has added social features, develop the O2O business, rumors of a stock-trading function and delays on the line, showed up with PayPal to take root social payments and areas such as mobile payments, financing, and payment will be set separately.

Ant treasure will be on existing financial markets what vibration?

1, thoroughly shuffle in the financial market.

In the area of monetary funds balance Po changed the rules in a year. Hung and beat before this Ant-gold suits and takes advantage of the traditional financial institutions, technology, user scale and complimentary strategy.

T+3 industry managed to redeem by ants jubao technical advantages to "T+1", and 1.2% Fund transaction costs have also been canceled before. This will allow online Fund sales compounded by weak profits, shuffle effect more obvious.

Top every day under the net wealth of the Fund before the net, sales in 2014 Fund surged 5.37 times times, total sale of 229.7 billion yuan revenue of 373 million Yuan, a loss of 5.65 million Yuan.

Relying on the net wealth of traffic, daily Fund net sales the largest independent sales organization, became a well-known online Fund supermarkets.

Ant-gold suit dimension attack, net wealth flow advantages, technical advantages, Ant-flow of gold clothing, and users will soon be translated into huge power forward. Balance Po 600 billion yuan a year, treasures from 0 to 260 billion a year, Ant funds sold on the treasure, will also be exponential growth, Ant gold service platform sales total financing amount will easily break a trillion yuan.

2, Ant ju Bao will be the first entry of the Fund, will this inlet flow becomes very important.

Fund are now more than 2000 companies in the domestic market, selling a variety of ways, such as direct Bank sales, because Ant gold take overwhelming advantage in the user, prior to its users than all of them.

Ants will be Fund flow entrance, similar to the control of information portal Baidu. Paul Frank iPad Mini Case

The result will be, good prices be higher search prices are getting higher and higher; relative to previous, more and more investors Fund can contact. Paul Frank iPad Mini Case

Among the new rules is still forming, cards in advance is important. Fund managers, should go to the Ant's headquarters?

3, direct investment in overseas assets of imagination

Based on previous performances, MA dad and Abacus Ant gold suit, never appear in front of little interest at this point, Ant treasure the future of imagination, is the stock trading and investments in overseas markets.

In the Ant on the treasure, has reserved a-shares and Hong Kong stocks and Wall Street entrance, believe that function already debugged, only policy is set, soon to go online.

Mutual recognition of mainland China and Hong Kong Fund entered into force on July 1, Hong Kong's funds through sales agencies and fund companies to enter the mainland market on the Mainland, could soon be in Ant treasure online, Hong Kong is an international financial centre, Hong Kong is behind the global assets of the Fund, therefore amounts to indirect open global investment channel for domestic investors.

Another direct channel, domestic fund companies through the QFII quota investment fund, which is a channel of direct investment of foreign assets by domestic investors, Yuan Leiming admitted will be launched in the third quarter foreign fund products.

Along with the appreciation of the US dollar, devaluation, overseas asset allocation for investors is an important way to spread the risk gets high yield.

Of course, once you have opened Internet channel overseas investment, before the convenience and efficiency of investment and minimal rapid outflow of funds on the traditional system of exchange controls will have a big impact.

Irresistible. Open a high yield and overseas investment channels, massive input from the PayPal user will Ant legions to buy buy buy.

MIU MIU iPhone 5 Case

Well, if this is you, where do you think IKEA likable? No, no, don't mention likes to see, the answer to the question, in fact, can be very simple, because IKEA sometimes does have ideas--for example, designer Sergey Komardenkov's new IKEA designs this stuff, let people buy, IKEA desk into a thermal power plant: MIU MIU iPhone 5 Case

This masterpiece based on two a premise, first, should be home has sale has a wireless charging component, can will you of desk into Wireless charging base; second, designer are found, including hot coffee zainei, and you of notebook, everyone of desk Shang, actually has many free have heat--they statistics found, usually of notebook computer, its energy probably is 40 w around, these energy General will to heat of form distributed out, if can will these hot are into electric......

So, on birth has this wonderful of creative, a thermoelectric conversion device, can and should be home of wireless charging component collaborative combat, dang you Office of when, smoothly will just bubble good of coffee put in table Shang, or thermoelectric conversion district just on in you winter can Dang warm hand treasure of computer following, physical law on began silently to work, will heat conversion for power, and once Wireless charging component began flashing signal, on representative has produced has must of power, then, will support Wireless charging of phone put charging district on can added power!
