batterie 18650 3500mah Manufacturers

Lithium battery manufacturers for electric vehicles: With more and more intelligent products, the application of lithium battery for electric vehicles will be more and more extensive, which can be said to be an important part of them. However, if you do not know the operation items during the use, it is likely to reduce their service life. What should we know when applying? Let's take a look at the answers given by lithium battery manufacturers.

When it comes to batteries, everyone is familiar with them. In today's era, batteries have become a necessity of life. People can not live without batteries.

In the past, all mobile power sources used 18650 batteries. 18650 batteries have gained the favor of many brands due to their light weight and large capacity. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power sources start using lithium polymer batteries?

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

Against the background of increasingly depleted oil resources and environmental pollution, electric vehicles have entered a period of rapid development. However, due to the high cost, short battery cycle life, short range and other problems of electric vehicles, further large-scale promotion of electric vehicles is also restricted.
