Abstract: Battery aging is one of the critical problems to be tackled in battery research, as it limits the power and energy capacity during the battery's life. Therefore, optimizing the design of battery systems requires a good understanding of aging behavior.
Accelerated aging at high temperatures may cause massive heat accumulation inside the battery, resulting in the thermal runaway of the battery, which is why the temperature rarely exceeds 60 °C in actual accelerated aging research. High-temperature cycling also affects the degradation of battery active materials.
It is necessary to investigate the battery aging process and deterioration model at the cell level, particularly how battery essential factors affect battery life and other important characteristic metrics like power and energy density. The aging process and deterioration model are also crucial at the battery system level.
Accelerated aging, as an efficient and economical method, can output sufficient cycling information in short time, which enables a rapid prediction of the lifetime of LIBs under various working stresses. Nevertheless, the prerequisite for accelerated aging-based battery lifetime prediction is the consistency of aging mechanisms.
