3.7v lithium ion battery cell Manufacturers

In the past, all mobile power supplies used 18650 batteries. Because of its light weight and large capacity, 18650 batteries have won the favor of many brands. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power supplies begin to use lithium polymer batteries?

Lithium battery has been widely used in the market today. Maybe many people do not know the correct operation of this product. In fact, its service life is generally 10 years, depending on the application environment and usual habits. It can be used for about 10 years under normal circumstances, but the capacity will slowly decrease in the later period. Each charge can be discharged for 300~500 times. In addition, how can the service life be extended? Let's take a look at the introduction given by the lithium battery manufacturer.

According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come

Electric cell refers to a single electrochemical cell containing positive and negative electrodes, which is not used directly. It is different from the battery which contains protective circuit and housing, and can be used directly. Generally speaking, it is a battery that removes the shell, and the rest is called the battery cell.

All lithium ion batteries, whether in the past or in recent years, including lithium polymer batteries, lithium iron phosphate batteries and so on, are very afraid of internal battery short circuit, external battery short circuit, overcharge these situations.
