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.

Lithium iron phosphate batteries have a variety of unique advantages such as high working voltage, high energy density, long circulation life, and environmental protection. They support unspeed extensions. After configured the energy storage system, large -scale power storage can be performed. Lithium iron phosphate battery energy storage system consists of lithium iron phosphate battery pack, battery management system (BMS), converter device (rectifier, inverter), monitoring system, transformer, etc.

As is known to all, BYD started from lithium iron phosphate battery and has stuck to this field for a long time. However, a statement recently issued by BYD was a surprise.

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?

In the secondary battery industry, lithium polymer batteries have occupied most of the market. At the same time, there are many modular batteries and battery packs in series and parallel. What are the differences between series and parallel batteries? Today, the editor will introduce it to you.
