How many models and specifications of the battery? In the end, there are several types, but in fact it is unclear, because each battery manufacturer has its own model specifications, and some customized battery models and specifications. The following introduces the naming of the lithium battery pack model specifications and the meaning of the letters and numbers on the battery, so that everyone has a better understanding of the battery model specifications.

The model name of the 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 slash should be added between the dimensions; if any of the three dimensions is less than 1mm, the letter t” shall be added in front of this dimension, and the unit of this dimension is one tenth of a millimeter.

ICP103450 represents a square secondary lithium battery pack, the cathode material is drilled, its thickness is about 10mm, width is about 34mm, and height is about 50mm.

ICPO8/34/150 Represents a square secondary lithium ion battery, the positive electrode material is drilled, 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 drilled , The thickness is about

0.7mm, the width is about 34mm, and the height is about 48mm.

The model name of the cylindrical lithium battery pack is composed of three letters and five digits, IEC61960 The rules governing cylindrical and square batteries are as follows:

Cylindrical lithium batteries, 3 letters followed by 5 numbers. 3 letters, I means built-in lithium ion, L means lithium metal or lithium alloy Electrode. The second letter represents the cathode material, C represents diamond, N represents nickel, M represents manganese, and V represents vanadium. The third letter is R represents cylindrical.

5 numbers, the first 2 The number indicates the diameter, the last 3 numbers indicate the height, and the unit is mm.

For example: ICR18650 is a general-purpose 18650 cylindrical battery with a diameter of 18mm and a height of 65mm, and 0 indicates a round shape.

3.6V is the indicator and the voltage is 3.6V

C is the discharge rate of the battery when it is discharged, the unit is mAh, and it is generally the discharge size or speed per unit time. For example, the battery capacity used After 1h discharge, it is called 1C discharge; after 5h discharge, it is called 0.2C discharge.
