ABSTRACT:
The present invention relates to a non-aqueous electrolyte secondary battery in which a spirally coiled battery element obtained by spirally coiling an anode (3) and a cathode (2) through a separator (4) is accommodated in a battery can (5) filled with a non-aqueous electrolyte. A fluoride MFn(M indicates at least one metal selected from between Cu, Ni, Ag, Ti, Sn and Cr, and n is an integer.) is included in the anode before an initial charging operation, and assuming that the initial charging capacity of the battery is Q [mAh] and a Faraday constant is F [C/mol], an amount m [mol] of the fluoride MFnincluded in the anode is located within a range represented by the following expressionin-line-formulae description="In-line Formulae" end="lead"?0.0036 Q
