What is the reason for the short life of high-rate polymer batteries

The reason for the short life of high-rate polymer batteries. This effect is generally related to ordinary batteries. In this respect, high-rate is still more advanced than ordinary batteries, and the high-current discharge of many high-rate batteries belongs to instantaneous discharge. Range, rather than continuous high-current discharge. But there is still a certain impact. There are two reasons. 1. Affect the positive and negative electrodes. Because the high-rate polymer batteries do a high-rate cycle, this will cause the lithium ions to react very quickly during high-rate charge and discharge. The specific point is that the lithium ions go from the positive electrode to the negative electrode or from the negative electrode to the positive electrode. The time becomes shorter, so that the consumption of positive and negative materials and electrolyte is relatively large, and it is reasonable for the battery life to be reduced. 2. Affecting the diaphragm Affecting the positive and negative electrodes and electrolyte is one aspect, and affecting the battery diaphragm is another aspect. This is actually an indirect result of the impact on the positive and negative electrodes and electrolyte. Lithium-ion batteries must constantly pass through the diaphragm holes during high-speed movement. For example, a diaphragm has a lifespan of 10 at normal lithium-ion battery traffic speed. In the case of high speed, it may be reduced to 5 years. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
