Hello, the weight of a lithium battery is linked to its capacity; for example, the current capacity of household lithium batteries is about 120 Wh/kg; there will be some differences in the weight of different lithium batteries; lithium battery capacity, you can estimate the weight based on the above method and vice versa.
Expansion: Capacity = thickness * width * length * K (K unit is mah/mm^3). Average density = battery capacity/weight of battery solution.
The K value range is (0.07 ~ 0.11). The K value depends on the size of the capacitance. The larger the capacity, the larger the K value. The smaller the capacity, the smaller the K. value (which can be understood as the larger the size, the larger the K value).
In the actual calculation, the K value can be set to 0.1 by default. For example, 103450LP (thickness 10mm, width 34mm, length 50mm), calculated capacity= 10*34*50*0.1 = 1700, the actual capacity is more than 1800mah, for example 603048LP (thickness 6mm, width 30mm, length 48mm), calculated capacity = 6*30*48*0, 1=864, real capacity can be 900mah.
Lithium batteries are divided into several types according to the structure of the outer packaging, including aluminum shell batteries, polymer batteries and cylindrical batteries.
AL is the abbreviation for aluminum. Aluminum means aluminum in Chinese. The lithium battery marked with an aluminum shell is.
Grade A generally refers to lithium batteries whose capacity, internal resistance, voltage and size all meet the standards. Grade B generally refers to battery capacity, internal resistance, voltage and size that do not meet standards. or several standards. The battery is a grade A downgraded product.
In general, manufacturersRegular cants use product A, while small businesses can use product B. After all, product B is cheaper.
