What are the performance requirements of high-rate batteries

High-rate battery performance requirements (1) Discharge performance The battery is fully charged at an ambient temperature of 25±5°C, and then cooled or heated to the detection temperature within 30 minutes. The battery is kept at this temperature for 3 hours before discharging. After a temperature test is completed, the battery is placed at 25±5°C for 2 hours and then recharged. It is proved that with different nominal magnifications, when detecting at the same magnification, the larger the nominal magnification, the higher the platform. (2) Cycle performance After the battery is fully charged under the condition of an ambient temperature of 25±5℃, put it aside for 10min, discharge to 3.0V at 10.0CmA or nominal rate current, put it aside for 10min, repeat the above steps to cycle until the battery discharge capacity continues for two more times. Times≤80% discharge capacity in the 3rd week. The test shows that the high-rate lithium battery has a long cycle life and superior high-rate discharge capability. (3) Charging capacity Digital batteries generally charge currents of 0.2C, 0.5C; high-rate batteries generally charge currents of 0.5C, 1C, and the maximum can reach 15C, which greatly improves the charging efficiency.
