Original Abstract Submitted
A secondary battery diagnosis method rapidly charges a secondary battery at a low temperature and stores the secondary battery in a range of 45° C. or higher and 70° C. or lower for a predetermined period. The method determines a degree of voltage drop of the secondary battery between before and after storing the secondary battery. The secondary battery includes a negative electrode in which an active material having an average operating potential of 1.0 VvsLi/Li or more occupies 50% by weight or more of a negative electrode active material-containing layer.
