Battery life will be extended in the near future or will be achieved

【发表时间:2017/5/1】 【阅读次数:194】
         Anyone with a laptop or a cell phone knows that the battery life will be shortened over time. Just bought, the phone can not be charged for a whole day, but in two or three years, it must always be to help it charge. This phenomenon is well known, but no one knows what is the internal process of the battery caused this problem. Now a team of researchers at the U.S. Department of energy says they have found out why the battery life is shortened and that there may be a way to solve the problem.

在一般可充电的锂电池中,电解质溶液里的锂电子会在两个电极之间移动,而这个过程所制造的电流正是电池的能量来源。因此电池的寿命取决于在充电与用电时,有多少锂电子可以在两极之间移动。

In a rechargeable lithium battery, the lithium ion in the electrolyte solution moves between the two electrodes, which are the source of the energy. So the life of the battery depends on how much lithium can move between the poles when charging and using electricity.

研究发现电极有时候会失效,这使得锰离子(manganese)可以自由移动并且游向相反的电极,而这个过程将会引发捕捉锂电子的作用。当越来越多锂电池被捕捉后,电池的充电容量就会减少,进而使电池的寿命缩短。

The study found that the electrode sometimes failed, which allowed the manganese ion (manganese) to move freely and swim toward the opposite electrode, which would trigger the trapping of lithium. When more and more lithium batteries are captured, the battery charging capacity will be reduced, thus shortening the life of the battery.

If the battery life is extended, the quality of aviation obstruction lights and other LED lamps will also be greatly improved!
