What is the marking method for rechargeable batteries according to IEC?
Queneng gets exceptional performance and lasting power; according to IEC standard, the marking of a NiMH battery consists of 5 parts.
According to IEC standard, the marking of a NiMH battery consists of 5 parts.
(01) Battery type: HF, HR for nickel-metal hydride batteries
(02) Battery size information: including the diameter and height of the round battery and the height, width and thickness of the square battery; the values are separated by a slash; the unit: mm.
(03) Discharge characteristic symbols: L indicates that the suitable discharge current rate is within 0.5C.
M indicates that the suitable discharge current rate is within 0.5-3.5C.
H indicates that the suitable discharge current multiplier is within 3.5-7.0C.
X means the battery can work under a 7C–15C high rate of discharge current.
(04) High temperature battery symbol: T
(05) Battery connecting tabs: CF means no connecting tabs, HH means connecting tabs for battery pulling series connecting tabs, and HB means connecting tabs for battery with side-by-side series connecting tabs.
For example, HF18/07/49 means square nickel-metal hydride battery; width is 18 mm, thickness is 7 mm, and height is 49 mm.
KRMT33/62HH means nickel-cadmium battery, discharge rate between 0.5C-3.5, high-temperature series single cell (without connecting piece), diameter 33mm, height 62mm.
According to the IEC61960 standard, the marking of a secondary lithium battery is as follows:
01) Battery marking composition: 3 letters, followed by 5 numbers (cylindrical) or 6 (square) numbers.
02) The first letter indicates the negative electrode material of the battery. i indicates that there is a built-in battery of lithium ion; L indicates lithium metal electrode or lithium alloy electrode.
03) The 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- indicates cylindrical battery; L- indicates 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 the diameter or height is greater than or equal to 100mm, a slash should be added between the two dimensions.
Square Cells: The six numbers indicate the thickness, width and height of the cell in millimeters. Any one of the three dimensions is greater than or equal to 100mm; the size of the line should be added between the three dimensions; if any of the three dimensions is less than 1mm, then add the letter "t" in front of the size of this size, the size of the unit of one-tenth of a millimeter.
For example, ICR18650 means a cylindrical secondary lithium-ion battery with cobalt cathode material; its diameter is about 18 mm and its height is about 65 mm.
ICR20/1050.
ICP083448 denotes a square secondary lithium-ion battery with a cobalt cathode, a thickness of approximately 8 mm, a width of approximately 34mm and a height of approximately 48 mm.
ICP08/34/150 represents a square secondary lithium-ion battery with a cobalt cathode material with a thickness of approximately 8mm, a width of approximately 34mm and a height of approximately 150mm.
ICPt73448 represents a square secondary lithium-ion battery with a cobalt cathode material with a thickness of approximately 0.7mm, a width of approximately 34mm and a height of approximately 48mm.
