The life of a lithium battery depends on the quality of the battery cell and the material of the battery. Choosing high-quality batteries and materials as well as excellent manufacturing technology can reduce battery loss and extend battery life to a certain extent.
As the number of cycles of lithium batteries increases, the life of lithium batteries is decreasing, and the battery capacity is gradually shrinking. The number of life cycles of a lithium battery is determined by the quality of the battery and the material of the battery.
- 1) Ternary material cycle times are about 800 times.
- 2) Cycle times of lithium iron phosphate is about 2500 times.
- 3) 3.7V 18650 cycle life can usually reach 500-1000 times, 3.2V 18650 cycle life can usually reach 2000 times. Of course, the premise is qualified batteries produced by regular manufacturers, If it is a defective or counterfeit battery, the life will be very short.
National standard requirements: Cells and battery packs of power batteries, after 500 complete cycles, it can still maintain a capacity of not less than 90% of the initial state, after 1000 charge and discharge cycles, it can still maintain no less than 80% of the capacity, this is the most basic requirement for the life of power batteries on the market.
