A 40 Ah lithium battery can generally achieve a discharge rate of 1 C. The current of 20 A is 0.5 C, which means the discharge time should be 2 hours with a current of 20 A. If it reaches the standard, the discharge time should be 2 hours. capacity meets standards. If it is not reached, it is because it lacks capacity.
Ternary polymer lithium batteries refer to lithium batteries whose cathode material uses lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary cathode material and precursor products of ternary composite cathode material, which are made of nickel salt, cobalt salt and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. Batteries with ternary materials as positive electrode are safer than lithium batteriesand cobalt oxide. the voltage is too low to be used on mobile phones (the cut-off voltage of mobile phones is generally around 3.0V), there will be an obvious feeling of insufficient capacity.
