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.

At present, lithium-ion batteries have become popular in the market, and a large number of lithium-ion batteries have adopted the form of multi-core series connection. Due to the individual differences of battery cells, it is impossible to achieve 100% balance between charging and discharging. Therefore, a complete set of charging management system is particularly necessary. This is the second function that smart lithium-ion batteries should have - perfect charge management and discharge management for lithium-ion batteries.

With the rapid development of the global electronic information industry today, Vietnam's electronic and smart home appliance market is ushering in unprecedented development opportunities.
