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

According to the IEC standard, the identification of nickel-metal hydride batteries consists of 5 parts.
01) Battery type: HF, HR means NiMH battery

02) Battery size information: including the diameter, height of the round battery, height, width, thickness of the square battery, and a slash between the values
spaced, unit: mm
03) Discharge characteristic symbol: L means the suitable discharge current rate is within 0.5C
M indicates that the suitable discharge current rate is within 0.5-3.5C
H means the suitable discharge current rate is within 3.5-7.0C
X means that the battery can work under the high rate discharge current of 7C-15C
04) High temperature battery symbol: represented by T
05) The battery connection piece means: CF means no connection piece, HH means the connection piece for battery pull-shaped series connection piece, HB means battery belt
Connection piece for side-by-side series connection.
For example: HF18/07/49 means square NiMH battery, width is 18mm, thickness is 7mm, height is 49mm,
KRMT33/62HH means nickel-cadmium battery, discharge rate is between 0.5C-3.5, high temperature series single battery (without connecting piece), diameter
33mm with a height of 62mm.
According to the IEC61960 standard, the identification of secondary lithium batteries is as follows:
01) The battery identification consists of 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 ion with built-in battery; L—represents 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
electrode; V—the 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 indicate the diameter and height of the battery respectively. Diameter is in millimeters and height is in ten
one-third 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. Any of the three dimensions is greater than or equal to
When the size is 100mm, a slash should be added between the dimensions; if any of the three dimensions is less than 1mm, the letter "t" should be added before the size.
Bits are tenths of a millimeter.
For example: ICR18650 represents a cylindrical secondary lithium ion battery, the positive electrode 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 positive electrode material is cobalt, the thickness is about 8mm, the width is about 34mm, and the height is about 34mm.
About 48mm.
ICP08/34/150 represents a square secondary lithium-ion battery, the positive electrode material is cobalt, the thickness is about 8mm, the width is about 34mm,
Height is about 150mm.
ICPt73448 represents a square secondary lithium-ion battery, the positive electrode material is cobalt, the thickness is about 0.7mm, the width is about 34mm, and the height is about 0.7mm.
about 48mm
