3.7v 120mah battery Manufacturers

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.

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?
