| 摘要 |
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 MF<SUB>n </SUB>(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 MF<SUB>n </SUB>included in the anode is located within a range represented by the following expression <?in-line-formulae description="In-line Formulae" end="lead"?>0.0036 Q/nF<=m<=0.36 Q/nF.<?in-line-formulae description="In-line Formulae" end="tail"?>
