Introduction to the identification of lithium-ion battery cells

1. Lithium-ion battery logo composition: 3 letters followed by 5 numbers (cylindrical) or 6 (square) numbers. 2. The first letter: indicates the negative electrode material of the battery. I represents a lithium ion with a built-in battery; L represents a lithium metal electrode or a lithium alloy electrode. 3. The second letter: indicates the cathode material of the battery. C electrode based on cobalt; N electrode based on nickel; M electrode based on manganese; V electrode based on vanadium. 4. The third letter: indicates the shape of the battery. R represents a cylindrical battery; L represents a square battery. 5. Numbers: Cylindrical battery: 5 numbers respectively indicate the diameter and height of the battery. The unit of diameter is millimeter and the unit of height is tenth of a millimeter. When any dimension of diameter or height is greater than or equal to 100mm, a diagonal line should be added between the two dimensions. Square battery: 6 numbers indicate the thickness, width and height of the battery, in millimeters. When any of the three dimensions is greater than or equal to 100mm, a diagonal line should be added between the dimensions; if any of the three dimensions is less than 1mm, the letter t is added before this dimension, and the unit of this dimension is one tenth of a millimeter. For example: ICR18650 represents a cylindrical secondary lithium-ion battery, the cathode material is cobalt, its diameter is about 18mm, and its height is about 65mm. ICR20/1050. ICP103450 represents a square secondary lithium ion battery, the cathode material is cobalt, its thickness is about 10mm, the width is about 34mm, and the height is about 50mm. ICP08/34/150 represents a square secondary lithium-ion battery, the cathode material is cobalt, its thickness is about 8mm, the width is about 34mm, and the height is about 150mm. ICPt73448 represents a square secondary lithium ion battery, the cathode material is cobalt, its thickness is about 0.7mm, the width is about 34mm, and the height is about 48mm.
