What is the identification method of rechargeable batteries specified by IEC?

According to the IEC standard, the identification of nickel-hydrogen batteries consists of five parts. 01) Battery type: HF and HR refer to nickel-hydrogen battery

02) Battery size data: including the diameter and height of the round battery, the height, width and thickness of the square battery, and the values are separated by slashes, unit: mm 03) Discharge characteristic symbol: L indicates that the suitable discharge current rate is within 0.5C M represents a suitable discharge current rate within 0.5-3.5C H represents a suitable discharge current rate within 3.5-7.0 C X indicates that the battery can operate at a high rate of discharge current of 7C-15C 04) High-temperature cell symbol: T 05) The battery connecting piece represents: CF represents no connecting piece, HH represents the connecting piece for the battery pull-shaped series connecting piece, and HB represents the connecting piece for the battery strip side-by-side series connection. For example, HF18/07/49 represents a square nickel-metal hydride battery with a width of 18 mm, a thickness of 7 mm, and a height of 49 mm. KRMT33/62HH refers to nickel-cadmium battery with discharge rate between 0.5C-3.5, high-temperature series single battery (without connecting piece), diameter of 33 mm and height of 62 mm. According to IEC61960 standard, the secondary lithium battery is marked as follows: 01) Battery identification consists of 3 letters followed by 5 numbers (cylindrical) or 6 numbers (square). 02) The first letter indicates the negative electrode material of the battery. I-indicates lithium ion with built-in battery; L-indicates lithium metal electrode or lithium alloy electrode. 03) Second letter: indicates the positive electrode material of the battery. C — Cobalt based electrode; N — Nickel based electrode; M — Manganese based electrode; V — Vanadium based electrode. 04) Third letter: indicates the shape of the battery. R represents cylindrical battery; L represents square battery. 05) Numbers: Cylindrical cell: 5 numbers indicate the diameter and height of the cell, respectively. The diameter is in millimeters and the height is in tenths of a millimeter. When either dimension is greater than or equal to 100 mm in diameter or height, a diagonal line shall be added between the two dimensions. Square battery: 6 numbers represent the thickness, width and height of the battery respectively, and the unit is mm. If any one of the three dimensions is greater than or equal to 100mm, a diagonal line shall be added between the dimensions; if any one of the three dimensions is less than 1mm, the letter "t" shall be added before the dimension, and the unit of the dimension shall be one tenth of a millimeter. For example, ICR18650 represents a cylindrical secondary lithium-ion battery with a cathode material of cobalt having a diameter of about 18 mm and a height of about 65 mm. ICR20/1050。 ICP083448 represents a square secondary lithium ion battery, the cathode material is cobalt, the thickness is about 8 mm, the width is about 34 mm, and the height is about 48 mm. ICP08/34/150 represents a prismatic secondary lithium ion battery having a positive electrode material of cobalt and having a thickness of about 8 mm, a width of about 34 mm, and a height of about 150 mm. ICPt73448 represents a prismatic secondary lithium-ion battery having a cathode material of cobalt with a thickness of about 0.7 mm, a width of about 34 mm, and a height of about 48 mm.
