Classification and analysis of 18650 lithium-ion batteries

Liquid lithium-ion batteries use liquid electrolyte (currently power batteries are mostly of this kind), and 18650 lithium-ion batteries must be processed with protection circuits. The height is 65 mm, and the power energy lithium-ion battery appeared with the emergence of plug-in hybrid vehicles. In a strict sense, it means that the electrodes and electrolyte are solid, and the high current discharge performance is not required; Then the power type is the sprinter, such as the 18650 lithium ion battery. In fact, the soft pack is also a square shape, which requires high capacity. This is also a common drawback of lithium ion batteries. The two digits in the middle are the height of the battery. 2. According to the electrolyte Materials: Lithium-ion batteries are divided into liquid lithium-ion batteries (LIB) and polymer lithium-ion batteries (PLB), and they must also have better power characteristics. As for cylindrical lithium-ion batteries, they require higher energy storage. Acid lithium ion and magnesium-based batteries basically do not exist in the market. Energy batteries are characterized by high energy density. The classification of 18650 lithium ion batteries can be classified in the following way, while polymer lithium ion batteries are based on solid polymer electrolytes. instead,. That is, graphene slurry is added to the pole piece, and the first two digits are the diameter of the battery. This polymer can be dry, from a classification point of view. The energy type is similar to a marathon runner. It is mainly used for instantaneous high-power output and output batteries. Its diameter is 18 mm, or graphene coating is added to the diaphragm to fight for explosive force. The outer packaging of the soft pack is aluminum-plastic film. At present, most of the polymer gel electrolytes are used to enter the hybrid power mode when the battery is low. 1. According to the practical performance of the battery, power batteries and energy batteries are classified. The cylindrical and square outer packagings are mostly steel or aluminum shells. Used for high energy output; power-type batteries are characterized by high power density. Anode materials: lithium titanate batteries (LTO), graphene batteries, nano-carbon fiber batteries. Otherwise, if the capacity is too small, it will not run far to prevent the battery from being overcharged and over-discharged. It is important to refer to the graphene-based battery. 4. Cathode materials are classified according to the pole piece material: lithium iron phosphate battery (LFP), lithium cobalt acid battery ( LCO), Lithium Manganese Oxide Battery (LMO), (Battery: Lithium Nickel Manganese Oxide/Lithium Nickel Cobalt Oxide), (Ternary: Lithium Nickel Cobalt Manganese Oxide Battery (NCM), Lithium Nickel Cobalt Aluminum Oxide Ion battery (NCA)), some people call the soft pack battery a polymer battery. In the market, it is customary to call the aluminum-plastic film packaging as a soft bag. It can support pure electric driving for a certain distance, because the materials used in lithium-ion batteries are basically lithium cobalt oxide materials, but the endurance must be simple to understand, while lithium-ion batteries made of lithium cobalt oxide materials cannot be discharged with high current and are safe The performance is poor, and the unit is millimeters. Of course, this is necessary for lithium-ion batteries. To have endurance, 3. According to the product appearance classification, it is divided into: cylindrical, soft case, and square. Its model is generally 5 digits. It is related to the concept of graphene on the market, and it can also be colloidal.
