Classification and naming rules of lithium-ion batteries

Lithium-ion batteries are classified according to different standards, and there are many ways to classify lithium-ion batteries. Shape: prismatic battery (such as mobile phone lithium ion battery), cylindrical battery (such as 18650 battery); according to the outer packaging: aluminum lithium ion battery, steel lithium ion battery, soft lithium ion battery; according to electrolyte status: lithium ion battery (LIB) , Polymer lithium ion battery (PLB); According to cathode material: lithium cobalt acid (LiCoO2), lithium manganese acid (LiMn2O4), ternary lithium (LiNixCoyMnzO2), lithium iron phosphate (LiFePO4). Different manufacturers have different naming rules for lithium-ion batteries, but in general, everyone follows the same standard. According to the name of the battery, you can know the size of the battery and other information. According to IEC61960, the rules for cells, cylindrical cells and square cells are as follows: A. Cylindrical battery, 3 letters plus 5 numbers, 3 letters, the first letter represents the cathode material, I represents the lithium ion inside, and L represents Metal lithium or lithium alloy electrode. The second letter represents the cathode material, C represents cobalt, N represents nickel, M represents manganese, and V represents vanadium. The third letter R stands for cylinder. 5 digits. The first two digits indicate the diameter, the last three digits indicate the height, in millimeters. Square battery, 3 letters + 6 numbers and 3 letters. The first two letters have the same meaning as the cylinder. There are six numbers. The first two represent thickness, the middle two represent width, and the last two represent height (length). The unit is also mm. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete.
