Battery life and charging have always been something in our mind. We always look for places where you can charge, I am afraid that my smartphone is out of power, and battery life has always been an important factor in our purchase of new mobile phones. All companies are looking for methods for improving battery performance.

Recently, the research team from my country and the United States won a breakthrough discovery, which will bring longer to people in the future, better performance. The battery under the new technology has four times the battery in the market in the market. However, this is not to say that the charging time of this battery is also extended to 4 times the current battery charging time.

It is reported that chemical substances in this new battery are slow to slow on existing batteries. It is understood that Dr. Wangchangan, Tsinghua University, Dr.

Liju, of MIT, in the process of studying how to remove the oxidized coating from aluminum nanoparticles,. Dr. Wang and Dr.

Li are materials scientists. They have studied aluminum micro particles for a long time. Although this metal has good conductivity, this conductivity is lowered as the surface oxide is formed when it is exposed to air.

This layer of oxide is irrelevant to the large object, but related to miniature particles, it is very close, so the two researchers decided to find out the surface oxide layer of the nanoparticles. Two researchers choose to immerse this particle in a mixture of sulfuric acid and sulfate. This is to turn the alumina of the surface into titanium oxide-the conductivity of the latter.

In this process, a batch of aluminum nanoparticles in acidic mixture "survive time" is more than a few hours than they expect. Through this experiment, researchers believe that aluminum with a titanium oxide protective layer can replace graphite anode. In a conventional lithium ion battery, the graphite anode is expanded and contracted during the lithium ion motion, but this will also be accompanied by the slow attenuation of the battery.

Slowly, lithium ions form a compound on top of the electrode, so that the battery starts to lose charging capabilities. The problem of the battery used in the market is that the shape of the anode will change, and then it will get rid of the lithium compound layer formed on the upper surface, which in turn has caused more lithium ions to be destroyed. However, if it is changed to the aluminum nanoparticles with oxide, this problem can be solved.

At present, it is not clear when this battery is commercialized.
