News yesterday, a professor at the university of hunan famous in a paper just published in science magazine, developed fast charge, long cycle life of aluminium ion battery, will change the world.This thing on?Can really change our world?.

Aluminium ion battery consists of two electrodes: "a negatively charged by aluminum anode and a positively charged graphite cathode, people tried different materials used as cathode," and the Stanford team surprises simple solution to the problem is the use of graphite, graphite is essentially carbon.Some types of graphite materials can produce very good feature."Stanford team experimental battery installed aluminum anode and graphite cathode, electrolyte is actually the liquid salt at room temperature, so it is very safe. Our rechargeable battery can produce aluminum 2 volts. This is more than any voltage aluminum battery can produce higher."But our batteries can only achieve half of a typical lithium-ion battery voltage, if improve cathode materials should be able to eventually increase the voltage and energy density.So, we create the battery will satisfy all your vision battery characteristics: inexpensive electrode, safe, fast charging, flexible, and a long life.I have seen this kind of original new batteries, it's really exciting."The inventor professor dai said.

The study of other researchers also includes scientists from Taiwan's industrial technology research institute access limbang chang Lu Bingan and postdoctoral scholar Wu Yingpeng, hunan university.The king of the other authors include Stanford university deferred, GuanMing cloud, Michael angel, Chen Changxin and Yang Jiang;As well as the national Taiwan normal university obing Joe.The research backed by the U.S. department of energy (doe), Taiwan's industrial technology research institute, the global climate and energy project at Stanford, Stanford shooter walcott energy research institute, and the support of the ministry of education.

Contrast two reports, we can see that the project is indeed institutions such as the U.S. department of energy (doe) provide a comprehensive research project resources, hunan university professor lu is one of the researchers.This is a scientific research project in the United States, instead of hunan university, disseminated in a suspected title party.

Aluminum ion battery technology breakthrough?

Actually aluminum batteries have long been believed to have a promising future in the study, because of its great potential in the energy density.But so far, the aluminum is only to be used as a metal fuel battery, battery is not charging, but in the aluminum electrodes to fill.What run hundreds of kilometers in the former period of aluminum battery cars say is this.

Aluminum battery rechargeable batteries don't have to do, on the one hand, is a poor cycle life, on the one hand, being too slow, not practical.There is a fatal defect is the inside of the aluminum electrolyte ions is not stable, easy to react at risk.These weaknesses make aluminum battery has not been practical.

And information from paper, Stanford this project developed a special kind of graphite anode materials, can quick charge.Didn't say clear graphene in the news, but over the years there have been many made negative graphene materials, improve lithium battery charging speed of the news, a Spanish university has done even the point of loading test.

However, most of the graphene anode cycle life is very short, Stanford this 7500 times attenuation is a miracle.If the data is really that have made a breakthrough in the material.In addition, Stanford has found a suitable electrolyte, can ensure the safety of the battery, if Dr Wear not lying, the battery than lithium ion battery safety, it is very rare.So, the aluminum ion battery actually progress on material, new anode and electrolyte produced ideal aluminum ion battery performance.

How far is it from the practical?

We have noticed that the inventor also said that the battery is a prototype, rather than the finished product, problems are still a lot.Aluminum battery was theoretical capacity is very high, but the inventor said to further increase the energy density, suggesting that at least experiment energy density is insufficient, and aluminum battery power density was also have a poor sense of direction, the voltage is not high also, this limits the scope of its use.Although the cycles, charging speed, but the battery is poor, poor power, in many places.Such as high volume requirements of mobile phone battery.

But in electric cars, electric buses, in particular, the long life of fast charging cells is promising.In addition to technical problems, from the laboratory to production also need a long process, production line how to set up, how to control the quality, the new material to solve how to maintain consistency.

As the inventor said, now only have a good shape, may develop the ideal battery.Much cheaper than lithium aluminum and graphite is not expensive, as long as the aluminium ion battery energy density, power density and so on indicators tied lithium ion battery, rely on the advantage of other technical indicators and cost can be completely for lithium ion batteries.That was really changed our world.

At present, the aluminum ion battery is only a gimmick, and it will be the new energy of human hope in the future.
Ctech will always keep us informed and do the best in the battery field, and make big progress
