18650 Lithium battery naming rules
Nowadays, there are many kinds of brands in the lithium battery market. Giving a "good name" to a lithium battery product will not only add value to the product itself, but also become a selling point in the market.
When naming lithium battery products, it is an important part of the enterprise naming system. Picking a name that can match both the performance characteristics of the product and the psychological needs of consumers will undoubtedly improve the popularity and competitiveness of the product. But the name of the product cannot be arbitrary, and he also follows certain rules.
Different battery packer manufacturers have different naming rules, but everyone follows a unified standard for general batteries. According to the name of the battery, you can know the size of the battery and other information. According to IEC61960, the rules for cells, cylindrical and prismatic batteries are as follows:
Cylindrical battery, 3 letters followed by 5 numbers,
3 letters, the first letter indicates negative electrode material, I indicates built-in lithium ion, L indicates lithium metal or lithium alloy electrode. The second letter refers to the cathode material, C refers to cobalt, N refers to nickel, M refers to manganese, and V refers to vanadium. The third letter is R for cylindrical.
5 numbers, the first 2 numbers represent the diameter, and the last 3 numbers represent the height, all in mm.
Square battery, 3 letters + 6 numbers
3 letters, the first two letters have the same meaning as cylindrical, and the last letter is P, which means square.
6 numbers, the first 2 numbers represent the thickness, the middle 2 numbers represent the width, and the last 2 numbers represent the height (length), and the unit is also mm.
An example is as follows:
(1) ICR 18650 is a general-purpose 18650 cylindrical battery with a diameter of 18mm and a height of 65mm;
(2) ICP 053353 is a square battery with a thickness of 5mm, a width of 33mm and a height (length) of 53mm.
The above is the article sharing of all lithium battery naming rules.
