At present, the battery that restricts the further development of mobile phones is a battery. Although scientists have studied a lot of new technologies, it is very disappointing that there is no large-scale commercial use.

After the new mobile phone has been bought for a long time, it will find that the battery life is reduced a lot. Why does the lithium battery have this problem? The scientists finally got to know the problem and found the solution.

BGR reported that scientists from the US Department of Energy found that lithium batteries travel through the electrolytes of the yin and yang through lithium ions, thereby generating electricity for the equipment, and the decline in battery life is actually the performance of "reduction".

Lithium battery "shrinkage" is simply understood as the volume of lithium ions running back and forth during charging and discharging. When manganese ions are stripped from the cathode of the battery, they react with the electrolyte near the anode of the battery and capture lithium ions. However, the material of the battery electrode often breaks and decomposes, which causes a lot of manganese ions to run in reverse, thereby capturing more. More lithium ions.

In the long run, more and more lithium ions are trapped by manganese ions, which leads to a decline in battery life. Since we know that the principle scientists are studying countermeasures, there is no new battery technology to launch, and the secret to let lithium batteries continue to maintain high battery life is also extremely Good thing.
