At present, there is no recognized effective sorting method for retired batteries, and most of them still take capacity and internal resistance as sorting criteria, which is utilized for fresh batteries sorting after they are produced.
Battery sorting has traditionally relied on standard tests to collect data on capacity, internal resistance and other characteristics, facilitating a straightforward yet time-consuming single-parameter sorting method. This approach, while practical, only ensures the consistency of the battery in a static state .

The experiments to validate the effectiveness of the two-stage sorting method showed that its usage significantly improved the consistency and cycle life of the battery modules compared with the traditional single-stage sorting method. The capacity degradation Q 1n, measured in ampere-hours, was calculated as follows:
Step 1: Perform a feature extraction experiment on the second-use batteries that need to be sorted, so as to extract the sorting characteristic parameters of each battery. capacity test, HPPC test and low current discharging experiment are conducted to determine battery capacity, internal resistance and C loss, which is caused by LAM.
Sorting of second-use batteries is a necessary before grouping. Many factors, such as operating conditions, ambient temperature and cell inconsistency will affect the cell aging. Therefore, sorting factors for second-use batteries are needed to ensure the pack performance and satisfy the requirement for second-use operation.
