Lithium battery model specifications model list
What are the models and specifications of lithium-ion battery cells?
How many types of battery are there? In the final analysis, there are several, in fact, it is unclear, because each battery manufacturer has its own model specifications, and there are some customized battery specifications. The following introduces the name of the lithium battery model specifications and the meaning of the letters and numbers above the battery, so that everyone has a better understanding of the battery model specifications.

Cylindrical lithium battery model specifications
The model name of the cylindrical lithium battery is composed of three letters and five digits, and IEC61960 stipulates the rules for cylindrical and square batteries as follows:
Cylindrical lithium battery, three letters followed by five numbers. Three letters, I for built-in lithium ion, L for lithium metal or lithium alloy electrode. The second letter represents the anode material, C for drill, N for nickel, M for manganese, and V for vanadium. The third letter is R for cylindrical shape.
5 numbers, the first 2 numbers indicate the diameter, the last 3 numbers indicate the height, all in mm.
For example: ICR18650 is a diameter of 18mm, a height of 65mm, 0 indicates a circular general purpose 18650 cylindrical battery.
3.6V indicates that the voltage is 3.6V.
C is the discharge rate when the battery is discharged, the unit mAh, which is commonly said to be the discharge size or speed per unit time. For example, when the battery capacity 1h is discharged, it is called 1C discharge; After 5h discharge, it is called 0.2C discharge.

Square lithium battery model specifications
The model name of the square battery: six numbers respectively 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, which is measured in one-tenth of a millimeter.
ICP103450 represents a square secondary lithium-ion battery, the positive electrode material is a drill, its thickness is about 10mm, the width is about 34mm, and the height is about 50mm.
ICPO8/34/150 represents a square secondary lithium-ion battery, the positive electrode material is a drill, 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 positive electrode material is a drill, its thickness is about 0.7mm, the width is about 34mm and the height is about 48mm.
