Battery Manufactory

First, the state of the battery itself. For example, are there any problems in the production process, such as the quality of raw materials, manufacturing process, or battery aging. If it is a new battery, it may not be activated yet, and the active substances inside have not fully played their role, resulting in low initial discharge capacity. 1. The battery is not fully activated Cause: Some batteries (such as lithium-ion batteries and nickel-metal hydride batteries) require a complete charge and discharge cycle before the first use to activate the electrode material, fully infiltrate the electrolyte, and improve the utilization rate of the active material. Solution: a. Perform 2-3 complete charge and discharge cycles (0.2C~0.5C rate) as recommended by the manufacturer. b. Avoid using fast charge or high-rate discharge directly before the first discharge.   2. Influence of test environment temperature Cause: Low temperature (such as below 10℃) will significan...
