About 18650 battery classification

1. According to the practical performance of the battery, power battery and energy battery are classified. Energy batteries have the characteristics of high energy density, and the key is high energy output. Power batteries have increased with the advent of electric hybrid vehicles. It requires the battery to store high kinetic energy, can be suitable for the distance of pure electric vehicles, and has good output power characteristics, and enters the hybrid mode of oil and electricity in the low power consumption mode. I also briefly explained to people: Similar to a marathon runner, it has physical strength, a large current that regulates large capacity, and has a small charge and discharge characteristics; then the output power type is a sprinter, the battle is violent, but the physical strength is stronger Or run very close with a small capacity. 2. According to the electrolyte material, lithium batteries are divided into liquid lithium batteries (lib) and polymer lithium batteries (plb). Liquid lithium batteries are used for liquid electrolyte solutions (essentially used for power-driven rechargeable batteries). This polymer can be dry or colloidal, most of the current stage of choice for polymer electrolyte solutions. In the case of solid-state batteries, the exact meaning is that both the level and the electrolyte are solid. 3. Classified by commodity type: Divided into: cylinder, soft bag, square. Cylindrical and square outer packagings are often made of aluminum or aluminum. The outer packaging of the soft pack is an aluminum plastic film. In fact, the soft pack is also a square shape. The aluminum-plastic packaging used in the sales market is called a soft pack. Some people call the soft pack a polymer lithium battery. Regarding cylindrical lithium batteries, the model specification is generally 5 digits. The first two are straight, and the middle two are aspect ratios. The unit is millimeters. For example, 18650 lithium ion has a diameter of 18 mm and a height of 65 mm. 4. According to the electrode material: battery cathode material: lithium iron phosphate battery (lfp), lithium cobalt oxide battery (LCO), lithium manganese oxide battery (LMO), (binary battery: lithium nickel manganate/lithium nickel cobalt oxide), (Ternary: Nickel Cobalt Manganese Lithium Battery (NCM), Nickel Cobalt Aluminum Oxide Battery (NCA)). Anode material: lithium titanate battery (LTO), graphene battery, nano carbon fiber battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
