Lithium battery performance degradation

Lithium battery is the most widely used batteries on the market at present, mobile devices basically use lithium batteries, but we also know, lithium battery is not durable, doesn't have long service life, and it is not useful enough after a long time usage, power will reduce. Why does lithium battery have performance degradation? In order to research this problem, a national laboratory scientist in the United States made an observation. A powerful microscope was used to observe the charge and discharge of lithium battery and obtain the real-time state. What is the reason?

The scientists observed that the use of the battery would create pressure, which would cause the electrode to rupture. Each charge and discharge cycle will leave traces of lithium on the outside of the electrode, which is equivalent to the lithium is dead, so it can not continue to play its role, so it will not be used when charging, which will cause a drop in capacity. During the observation, it was also found that there would be a blocking phenomenon on this side. The interlayer of solid electrolyte would form on the electrode surface, which was the cause of the blocking, which directly affected the charging capacity of the battery. The problem has been found and how to solve it.

If we want to solve these problems fundamentally, then we need to look for the essence of battery, which is the material. Or find elements that can be replaced. Now scientists are looking for breakthrough from the aspects of development, the new materials of lithium-ion batteries were find out, the future of new type of lithium battery research and development and put into use, also will come true, and alternatives to research and development has never stopped, these metal magnesium, aluminum batteries are positive breach I hope to make the choice of life, instead of lithium batteries but are also in the experiment.
