How many model names does the lithium battery have? In fact, it's not clear at this time, because each battery manufacturer has its own model specifications and some custom battery models. The following introduces the name of the lithium-ion battery model and the meaning of the letters and numbers on the battery, so that everyone can better understand the battery model specifications.

Name of the square battery model: 6 numbers indicate the thickness, width and height of the battery, respectively, in millimeters. When any of the three dimensions is greater than or equal to 100mm, a symbol / 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.

"I" indicates that there is a built-in lithium ion, and "L" indicates a lithium metal or lithium alloy electrode. The second letter indicates the cathode material, C indicates cobalt, N indicates nickel, M indicates manganese, and V indicates vanadium. The third letter “P” is a square battery.

For example:

ICP103450 represents a square secondary lithium-ion battery. The positive electrode material is cobalt. Its thickness is about 10mm, its width is about 34mm, and its height is about 50mm.

ICP08 / 34/150 represents a square secondary lithium-ion battery. The positive electrode material is cobalt. Its thickness is about 8mm, its width is about 34mm, and its height is about 150mm.

ICPt73448 represents a square secondary lithium-ion battery. The positive electrode material is cobalt. Its thickness is about 0.7mm, its width is about 34mm, and its height is about 48mm.

The cylindrical lithium-ion battery model name is composed of three letters and five digits. IEC61960 stipulates the rules for cylindrical batteries as follows:

Cylindrical lithium-ion battery with 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 indicates the cathode material, C indicates cobalt, N indicates nickel, M indicates manganese, and V indicates vanadium. The third letter R is cylindrical.

5 numbers, the first 2 numbers indicate 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.

3.6V is the indicator that the normal voltage is 3.6V

"C" is the discharge rate when the battery is discharged. The unit is mAh. In popular terms, it is the discharge capacity or speed in a unit time. For example, if the battery capacity is discharged in 1h, it is called 1C discharge; if it is discharged in 5h, it is called 0.2C discharge.
