The nickel content is 12%, the cobalt content is 3% and the lithium content is 2%. According to inquiries from electronic enthusiasts, the nickel content in the ternary lithium battery is 12%, the cobalt content is 3%, and the lithium content is 2%. The lithium battery is a ternary lithium polymer. Its positive electrode material is lithium nickel. Cobalt manganate and negative electrode material. Mainly graphite, and the electrolyte is mainly lithium hexafluorophosphate.
I want to use a lithium battery to power a 150W/12V electrical device for 20 minutes. What size battery should I choose?
This is important, the larger the capacity, the greater the size and weight.
The capacity of the lithium polymer battery is related to the size of the model and depends on the thickness, width and length of the batteryterie. It also depends on the material and size of the battery. The actual calculation formula for lithium polymer battery capacity is very complicated and has a non-linear relationship with volume. There are many factors to consider, such as different materials, which have a big impact on the actual capacity. The larger the size, the higher the capacity-to-volume ratio.
3.2 V 56.32 Wh).
If it is 18650 polymer lithium battery, generally 3.7V 2600mAh, 2 parallel and 3 series 6-cell batteries, 3.7V × 3 = 11.1 V, 5200 mAh, 11.1 V × 5200 mAh = 57.72 Wh, it can be used for 20 minutes. The voltage of the 4 strings is 3.7 V × 4 = 14.8 V. The voltage may be too high. A single 18650 lithium battery will not have a capacity of 4800 mAh.
