18650 lithium battery manufacturers expose the rules for naming lithium batteries

As mentioned in the naming rules for lithium batteries exposed by 18650 lithium battery manufacturers, the naming rules for lithium batteries are generally divided into 5 points, of which size, cathode material, external shape and are important. These points provide a clear definition for the naming rules for lithium batteries. Standards of performance; 1. Lithium battery shape and the main shape of the positive electrode material system: the square is represented by P and the cylindrical shape is represented by R; the positive electrode material: lithium iron phosphate is represented by IF; therefore, IFR represents lithium iron cylindrical battery. 2. Lithium battery cell size. Cylindrical cell size: consists of 5 digits. The first 2 digits represent the diameter of the cell and the third digits represent the height. The unit of diameter is millimeter and the unit of height is 1/10 millimeter; for example, 18650, 18 means that the diameter is 18mm and the height is 65mm. Square cell: It consists of 6 digits. The first 2 digits represent the thickness of the cell, the middle two digits represent the width, and the back two digits represent the height. The units are all millimeters; for example, 1665120, 16 means the width is 16mm, and the width is 65mm. Height is 120mm; 3. Lithium battery cell type (working current) E is capacity type: discharge current ≤ 1C; N is conventional medium power type: 1C 45℃; Core cost distinction: D-type batteries: high-cost batteries; C-type batteries: low-cost batteries; cap appearance distinction: F-type batteries: flat-cap batteries; J-type batteries: pointed-cap batteries; Shell material distinction: steel shell S, aluminum shell A, and aluminum-plastic film flexible packaging P; other special requirements or composite type to distinguish cell types: add other letters or symbols to distinguish cells. Note: When naming, only the most important distinction is selected for naming. 5. The nominal capacity of a lithium battery cell consists of several digits, the unit is: mAh; for example: 2200mAh; Note: It is not the same as the capacity grade after the battery is divided. The capacity grade is the actual capacity data obtained after the capacity is divided. A certain range is divided into files, such as A1 battery cells. For example, the naming examples of the iron-lithium battery on the Shenzhen battery website are as follows: 1. Iron-lithium cylindrical battery; 2. The cell diameter is 18mm and the height is 65mm; 3. The capacity type battery; 4. The operating temperature is normal temperature; 5. The capacity is 1200mAh. Therefore, this battery cell is named: IFR18650P1200mAh battery. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
