Performance requirements for high rate lithium-ion batteries

(1) Discharge performance

High magnification lithium-ion batteries at ambient temperature of 25± Fully charge at 5 ℃, then cool or heat to test temperature within 30 minutes. Before discharge, the battery is maintained at this temperature for 3 hours. After completing a temperature experiment, the battery is at 25± Place at 5 ℃ for 2 hours before charging. Prove that different nominal magnification, when tested at the same magnification, the higher the nominal magnification, the higher the platform.

(2) Cyclic performance

High magnification lithium-ion batteries at ambient temperature of 25± After fully charging under the condition of 5 ℃, let it stand for 10 minutes and discharge to 3.0V with 10.0 CmA or nominal rate current. Let it stand for 10 minutes and repeat the above steps for cycling until the battery discharge capacity continues twice; 80% of the 3rd week discharge capacity. Experiments have shown that high rate lithium-ion batteries have a long cycle life and superior discharge capacity at high rates.
