Analysis on the classification of 18650 lithium batteries

18650 lithium battery classification processing 18650 lithium battery requires a maintenance line to prevent battery overcharge and discharge. Of course, this is necessary.Lithium batteries, a disadvantage of lithium batteries, because lithium batteries use data root lithium cobalt oxide, lithium cobalt oxide materials, lithium batteries cannot be discharged with high current, poor safety, from the classification, classification of 18650 lithium batteries The following methods can be used to classify. 1. According to the useful functions of the battery, classify the power battery and the energy battery. Energy batteries are characterized by high energy density and are mainly used for high-energy output; power lithium-ion 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 requires the battery to store higher energy, be able to support pure electric driving for a certain distance, and have better power characteristics, and become a hybrid form at low power. In brief, the energy type is similar to a marathon runner. It requires high capacity, not high current discharge function; therefore, power is for sprinters, and fighting is an explosion of power, so endurance is required, otherwise If the ability is too small, you can't run far. 2. According to the electrolyte data, lithium batteries are divided into liquid lithium batteries (LIB) and polymer lithium batteries (PLB). Liquid lithium batteries use liquid electrolytes (now common in power lithium-ion batteries). Lithium-ion polymer batteries are replaced by solid polymer electrolytes, which can be dry or colloidal, and are now mainly composed of 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. Cylindrical and square packaging are suitable for steel or aluminum shells. The outer packaging of the soft pack is aluminum-plastic film. In fact, the soft pack is also a square shape. The custom-made aluminum-plastic film packaging on the market is called a soft pack. Some people call the soft pack battery a polymer battery. Regarding cylindrical lithium batteries, it is generally 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. Classify positive data according to pole section data: lithium iron phosphate battery (LFP), lithium cobalt oxide battery (LCO), lithium manganese oxide battery (LMO), (binary battery: nickel oxide nickel lithium manganese oxide/nickel nickel cobalt oxide) Lithium), (ternary battery: nickel oxide nickel manganese lithium battery (NCM), nickel nickel aluminate lithium battery (NCA)). Cathode data: lithium titanate battery (LTO), graphene battery, carbon nanofiber battery. As far as the graphene concept on the market is concerned, the most important thing is a graphene-based battery, that is, graphene sizing on a polar sheet, or graphene coating on a 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.
