ABSTRACT:
In a non-aqueous electrolyte secondary cell, it is possible to control the irreversible capacity degradation which is caused when it is preserved under the condition of charging. The non-aqueous electrolyte secondary cell includes a positive electrode that is capable of doping and dedoping lithium and a negative electrode and non-aqueous electrolyte. Specifically, a monomethoxy benzene class compound is added to the non-aqueous electrolyte at a concentration ranging from 0.005 M to 0.5 M.
