A, An overview of the Polymer lithium battery Polymer lithium battery generally refers to Polymer lithium ion batteries。 According to the electrolyte materials that are used in lithium ion batteries, lithium ion batteries are divided into liquid lithium ion battery (Liquified Lithium – Ion Battery, LIB for short) and polymer lithium ion battery (Polymer Lithium – Ion Battery, for PLB) or plastic lithium ion battery (PlasTIcLithiumIonBatteries, for PLB)Is used in the polymer lithium ion battery cathode materials and liquid lithium ion is the same, the anode materials are divided into cobalt acid lithium, manganese acid lithium, ternary material and lithium iron phosphate material, negative extremely graphite, working principle of the battery is almost the same.
