Do you know the general classification of 18650 lithium batteries?

1. According to the practical performance 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 battery is accompanied by the emergence of plug-in hybrid vehicles. It requires the battery to store high energy, which can support pure electric driving for a certain distance, but also has good power characteristics, and enters the hybrid mode when the battery is low. Simply understand, the energy type is similar to a marathon runner. To have stamina, it requires high capacity and does not require high current discharge performance; then the power type is a sprinter, fighting for bursting power, but endurance is also necessary, otherwise the capacity is too large. You can't run far when you are young. 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, which can be dry or colloidal, and most of them currently use polymer gel electrolytes. Regarding solid-state batteries, in a strict sense it means that the electrodes and electrolyte are both solid. 3. According to the product appearance classification, it is divided 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 package as a soft pack, and some people call the soft pack battery a polymer battery.
