Abstract

A modification of the differential voltage analysis method is developed. It allows determination of the degradation mechanisms during charging of Li-ion batteries. A constant current (CC) with relatively high C-rate can be used in the analysis method. The modification of the differential voltage analysis method is based on measuring the heat generated during CC charging of Li-ion batteries. The advantages and the applicability of the presented modified differential voltage analysis (MDVA) method are verified by a comparison with currently existing and proven methods used in determining the Li-ion battery degradation mechanisms.
