Do you know the general classification of 18650 lithium-ion batteries?

1. According to the practical function of the battery, power battery and energy battery are classified. 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. The power energy lithium-ion battery is accompanied by the presentation of plug-in hybrid vehicles. It requires the battery to store high energy, can support pure electric driving for a period of time, but also has good power characteristics, and enters the hybrid power mode when the battery is low. Simple to understand, the energy type is similar to the marathon runner. To have endurance, it requires high capacity, and it does not require high power for the exile motor; then the power type is a sprinter, fighting for explosive power, but endurance must also be there, otherwise capacity It’s too young to run far. 2. According to the electrolyte material, lithium ion batteries are divided into liquid lithium ion batteries (LIB) and polymer lithium ion batteries (PLB). Liquid lithium-ion batteries use liquid electrolytes (currently power batteries are mostly of this type). Polymer lithium-ion batteries are replaced by solid polymer electrolytes, which can be dry or colloidal. At present, most of the polymer gel electrolytes are recycled. Regarding solid-state batteries, in a strict sense it means that the electrodes and electrolyte are both solid. 3. According to the appearance of the product, it is classified into: cylinder, soft bag, and square. Cylindrical and square outer packagings are mostly steel shells or aluminum shells. The outer packaging of the soft pack is aluminum-plastic film. In fact, the soft pack is also a square shape. In the market, it is customary to call the aluminum-plastic film packaging as a soft pack. Some people call the soft pack battery a polymer battery.
