Lithium electronic battery charging and discharging principle structure diagram
Basic characteristics and principle of lithium battery
The high-rate lithium polymer lithium battery uses a special structural design, uses a lamination process, and special optimized ratio of the electrolyte. Unlike the polymer lithium battery of the mobile phone,
the high-rate lithium polymer lithium battery has low internal resistance and discharge. High efficiency, large current discharge, fast charging, etc.; can be 3-5C fast charging, 80% of full charge in 12 minutes (matching special fast charger)
