Naming conventions for polymer lithium batteries.
Different manufacturers have different naming standards, but universal batteries are all based on the same standard, and the specifications and other information of the battery may be understood based on its name. IEC61960 requests the following standards for lithium battery cells, cylindrical and square batteries:
1. Cylindrical battery, 3 English letters followed by 5 data,
2.3 English letters, with letters indicating positive battery data, I indicating embedded lithium positive ions, and L indicating lithium metal data or lithium aluminum alloy battery level. The second English letter indicates positive battery data, C indicates cobalt, N indicates nickel, M indicates manganese, and V indicates vanadium. The third letter in English, R, indicates cylindrical shape.
3. Five data points, with the first two digits representing diameter and the last three digits representing aspect ratio, all in millimeters for enterprises.
4. Square battery, 3 English letters and 6 data
5.3 English letters, the actual meaning of the first two letters is the same as that of a cylinder, and the last English letter P indicates a square. 6.6 pieces of data, with the first two digits indicating thickness, the two adjacent digits indicating total width, and the last two digits indicating aspect ratio (true or false). The enterprise is also in mm. For example, (1) ICR18650 is a universal 18650 cylindrical battery with a diameter of 20mm and an aspect ratio of 65mm; (2) ICP053353 is a square battery with a thickness of 5 millimeters, a total width of 33 millimeters, and an aspect ratio (true or false) of 53 millimeters.
