  "textContent": "A method for standardizing a decommissioning definition of power batteries, including: obtaining power battery capacity data and SOH data; obtaining capacity degradation gradient by subtracting battery capacity of current charge-discharge cycle by battery capacity of previous charge-discharge cycle, and obtaining index of decommissioning (IoD) of power battery by dividing capacity degradation gradient by a square of SOH of current charge-discharge cycle; and when IoD is less than a set threshold, dismantling, disassembling and separating the power battery; otherwise, continuing to use the power battery. An aging state of battery is evaluated comprehensively based on two indexes—the SOH and the capacity degradation gradient, so that a new IoD of the battery is proposed. Each cell can be comprehensively evaluated according to various real-time states of battery, thereby achieving individual decommissioning, which ensures safe use of battery and increases the utilization rate of battery.",
