Moreover, the researches on the storage performance and decay mechanism of lithium-ion batteries have been focused on the cathode and the anode, where a series of reactions between both electrode materials and electrolyte, leading to an increase in capacitance loss and resistance of lithium-ion batteries during storage [32 ].
Battery capacity decay curve. Because the IC curve can represent the rate of change of capacity with voltage evolution, ICA is an important method used to analyze the degradation mechanism of batteries. ICA involves the derivative of capacity with respect to voltage and is calculated as shown in Eq.
After storing at 65 °C, the rate of internal resistance change of batteries increases, and the rate of capacity retention and recovery change decreases with the extension of storage time ( Table S1 ), which can be mainly ascribed to the deposition of dead Li and dissolution of Co during storage.
The dead Li in the anode increases linearly with the extension of storage time, which directly lead to capacity decay. 3. The decreasing recovered capacity and increasing capacity loss can be accounted for by the increased internal resistance of stored batteries under 100% SOC.
3. The decreasing recovered capacity and increasing capacity loss can be accounted for by the increased internal resistance of stored batteries under 100% SOC. To ensure the validity of the forecast, a storage time limit of up to 6 months is recommended.
