What types of 18650 lithium batteries? What are its advantages?

18650 lithium battery pack classification 1. According to the practical performance of the battery, it is classified into power-type batteries and energy-type batteries. Energy batteries are characterized by high energy density and are mainly used for high energy output; power batteries are characterized by high power density and are mainly used for batteries with instantaneous high power output and output. 2. According to the electrolyte material, lithium batteries are divided into liquid lithium batteries (LIB) and polymer lithium batteries (PLB). Liquid lithium batteries use liquid electrolytes (currently, power batteries are mostly of this type). Polymer lithium batteries are replaced by solid polymer electrolytes. This polymer can be dry or colloidal. At present, most of the polymer gel electrolytes are used. Regarding solid-state batteries, in a strict sense it means that the electrodes and electrolyte are both solid. 18650 lithium battery has the following advantages: 1. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment. 2. The series connection can be combined in series or parallel to form a 18650 lithium battery pack. 3. Small internal resistance. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. , Can reach the level of international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen storage batteries.
