18650 Lithium-Ion Battery Manufacturer Battery Naming Rules

18650 Lithium-Ion Battery Manufacturer Battery Naming Rules

The battery naming rules of 18650 lithium-ion battery manufacturers. The naming rules of 18650 lithium-ion batteries are generally divided 

into 5 points. Among them, battery standards, battery anode materials, battery external shapes, etc. are all important. They are in the naming of 

18650 lithium-ion batteries. plays an important purpose. Among many 18650 lithium-ion battery manufacturers, most of the 

18650 lithium-ion battery manufacturers have the same name, but many manufacturers have their own factory shrinkage rates, 

and others are very similar. For example, the battery manufacturer in Shenzhen named 18650 lithium ion battery.

1. Appearance: 

        Important shapes of 18650 lithium-ion battery and cathode material system: P square, R cylinder; 

   anode material: 

        lithium iron phosphate with IF; therefore, IFR stands for lithium iron cylindrical battery.

2.18650 lithium-ion battery standard cylindrical cell standard: 

    consists of 5 digits. The first two digits indicate the diameter of the battery, and the last three digits indicate the height of 

the battery. The diameter unit is mm and the height unit is 1/10mm. For example, 18650 and 18 means a diameter of 18mm and 

a height of 65mm. Square unit: consists of 6 digits, the first 2 digits indicate the thickness of the unit, the 

middle 2 digits indicate the width, the last 2 digits indicate the height, the unit is mm; such as 1665120, 16 indicates the width is 16mm, the 

width is 65mm, and the height is is 120mm;

3.18650 lithium-ion battery battery type (operating current)

    E is capacitive type: discharge current s1C.

    N is the conventional dielectric power type: 1C<discharge current<5C

    P is the power type: discharge current 25C.

4.Specially marked 18650 ion battery

    Use temperature difference: battery type

    L is low temperature type: working temperature <0°C

    R is normal temperature type: 0°Cs working temperature s45°C

    H is high temperature type: working temperature 45C

    cost difference

    D battery: high cost battery

    C battery: low cost battery

    F type battery: flat top battery

    Type J is a cap battery;

    Differences in shell materials: steel shell S, aluminum shell A, aluminum film flexible packaging P

Other Special Requirements or Composite Differential Cell Types: Differential Cells Involving Other Letters or Symbols

Note: Only state the most important differences between them

5. Nominal capacity 18650 lithium-ion battery

    It consists of several digits, the unit is: mAh; for example: 2200 mA:

    Note: The capacity level is different from the capacity level after cell capacity division. Capacity level is the actual capacity data obtained after dividing the volume according to a certain planning classification.

    For example, the A1 level unit, the iron carp ion battery is named as follows

    1. Iron cylindrical battery

    2. Battery diameter 18mm, height 65mm;

    3.Battery materials

    4. The working temperature is normal

    5. The capacity is 1200mah.

So the battery name of this battery is: 

    IFR18650P1200mAh battery
