About battery identification analysis

14. What is the marking method for rechargeable batteries specified by IEC? According to the IEC standard, the mark of Ni-MH battery consists of 5 parts. 01) Battery type: HF and HR indicate nickel-metal hydride batteries 02) Battery size information: including the diameter, height of the round battery, the height, width, thickness of the square battery, and the values u200bu200bare separated by slashes, unit: mm03) Discharge characteristic symbol: L indicates that the appropriate discharge current rate is within 0.5C, M indicates that the appropriate discharge current rate is within 0.5-3.5C, H indicates that the appropriate discharge current rate is within 3.5-7.0C, X indicates that the battery can discharge at a high rate of 7C-15C Work under current 04) High temperature battery symbol: T for 05) Battery connection piece: CF represents no connection piece, HH represents the connection piece for the battery pull-type series connection piece, HB represents the battery with the connection piece for side-by-side series connection. For example: HF18/07/49 represents a square nickel-metal hydride battery with a width of 18mm, a thickness of 7mm, and a height of 49mm. KRMT33/62HH represents a nickel-cadmium battery with a discharge rate of 0.5C-3.5. The high-temperature series single battery (without Connecting piece), diameter 33mm, height 62mm. According to the IEC61960 standard, the identification of secondary lithium-ion batteries is as follows: 01) The composition of the battery identification: 3 letters followed by 5 numbers (cylindrical) or 6 (square) numbers. 02) The first letter: indicates the negative electrode material of the battery. I represents lithium with a built-in battery; L represents a lithium ion metal electrode or a lithium ion alloy electrode. 03) The second letter: indicates the cathode material of the battery. C Cobalt-based electrode; N Nickel-based electrode; M Manganese-based electrode; V Vanadium-based electrode. 04) The third letter: indicates the shape of the battery. R represents a cylindrical battery; L represents a square battery. 05) 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. ICP083448 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 48mm. 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. What kind of packaging materials are used for the battery? 01) Non-dry meson (paper) such as fiber paper, double-sided tape 02) PVC film, trademark tube 03) Connecting piece: stainless steel piece, pure nickel piece, nickel-plated steel piece 04) Leading piece: stainless steel piece (easy to solder) pure Nickel sheet (spot welding) 05) Plugs 06) Protective components such as temperature control switches, overcurrent protectors, current limiting resistors 07) Carton, paper box 08) Plastic shell battery assembly, combination and design purpose is what? 01) Beautiful, brand 02) Battery voltage limitation. To obtain a higher voltage, multiple batteries need to be connected in series 03) Protect the battery to prevent short circuit and extend battery life 04) Size limitation 05) Easy to transport 06) Special function design, such as Waterproof, special appearance design, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
