NONAQUEOUS ELECTROLYTE SECONDARY CELL

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 ÄmAhÜ and a Faraday constant is F ÄC/molÜ, an amount m ÄmolÜ of the fluoride MFn included in the anode is located within a range represented by the following expression. 0.0036Q/nF ≤ m ≤ 0.36Q/nF
