Classification of 18650 lithium batteries

18650 lithium battery classification processing 18650 lithium battery must have a protection line to prevent the battery from overcharging and discharging. Of course, this is a must be a lithium battery, which is also a general disadvantage of lithium batteries, because the materials used are basic lithium cobalt oxide batteries, materials, lithium and lithium cobalt oxide materials, lithium batteries cannot be discharged at high current, and are safe from Classification, classification 18650 lithium batteries can be classified by the following methods. 1. According to the actual performance of the battery, classify power batteries and energy batteries. Energy batteries have the characteristics of high energy density and are mainly used for high energy output. Power-type batteries have the characteristics of high power density and are mainly used for instantaneous high-power output and output batteries. The electric lithium battery is accompanied by the emergence of plug-in hybrid vehicles. It needs the battery to store a large amount of energy, can support a series of pure electric drives, and has good power characteristics, and enters the hybrid mode when the battery is low. Simply understand, the type of energy is similar to that of a marathon runner. To have endurance means that high capacity is required, and the requirement for high current discharge performance is not high; therefore, strength is a sprinter, and fighting is an explosion of strength, and endurance is required, otherwise the ability is too small. You can't go far. 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 used in power lithium-ion batteries). Lithium-ion polymer batteries are replaced by solid polymer electrolytes, which can be dry or colloidal. At present, most of them are polymer gel electrolytes. In solid-state batteries, the electrodes and electrolyte are both solid. 3. According to the product appearance classification, it is divided into: cylinder, soft bag, square. Steel or aluminum shell for cylindrical and square packaging. The flexible packaging is aluminum-plastic film. In fact, the flexible packaging is square. The commonly used aluminum-plastic film packaging on the market is called flexible packaging, and some people call it a polymer battery. Regarding cylindrical lithium batteries, the model number is usually 5 digits. The first two digits are the diameter of the battery, and the middle two digits are the height of the battery. It's in millimeters. For example, a 18650 lithium battery has a diameter of 18 mm and a height of 65 mm. 4. Classification of cathode materials by pole piece material: lithium iron phosphate battery (LFP), lithium cobalt oxide battery (LCO), lithium manganese oxide battery (LMO), (binary battery: nickel nickel oxide lithium / nickel nickel cobalt lithium oxide) , (Ternary battery: nickel oxide nickel manganese lithium battery (NCM), nickel nickel aluminate lithium battery (NCA)). Cathode materials: lithium titanate batteries (LTO), graphene batteries, carbon nanofiber batteries. The concept of graphene on the market is important for graphene-based batteries, that is, graphene slurry is added to the electrode plate or a graphene coating is added to the membrane. Lithium nickelate and magnesium-based batteries do not exist in the market. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
