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.

New atom performance ARM processors have and top closer, but are worse and the mainstream core of the series by a mile, but taking into account the thermal power of 14W and 2W gap, which is understandable. Use it for routine minor Office enough and finally surface series can also run X86 program! Said performance flaw, is that it does not use the SSD, and broken eggs eMMC 4.5, which even with the eMMc 5.0 modern Android flagship.
