Abstract
The present invention provides a method for sorting lithium cells, which includes quick sorting and high-precision sorting. The method provided by the present invention can be used for quickly and accurately classifying cells based on self-discharge, and is applicable to large-scale self-discharge sorting due to low cost of adopted equipment. Through the quick sorting method and the high-precision sorting method in the present invention, cells with large self-discharge rates can be eliminated from a batch of cells, cells with similar self-discharge rates can be sorted into groups, and an application range is wider.
