What is the cell phone battery oxidation?
In fact, after the oxidation of the battery metal contact has a simple solution is to find a rubber paint metal touch several times, you can know the metal luster.
Battery metal contact after the performance of poor performance due to poor automatic shutdown, battery consumption fast, can not open the machine, charging slow, serious fever and so on. But the probability of oxidation is relatively small. Because copper is difficult to oxidize. The battery is also covered by a coating. Even if the oxidation is not serious.
As the name implies, the chemical reaction that occurs after contact with oxygen is called oxidation, and in fact anything has an oxidation process, and it is important that the length of the process is long.
