Abstract:
The present invention provides a non-aqueous electrolyte secondary battery comprising a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte, wherein the non-aqueous electrolyte comprises a non-aqueous solvent and lithium salt as an electrolyte, and wherein the non-aqueous solvent contains chain fluorinated carboxylic acid ester represented by the formula CH3COOCH2CH3-xFx (wherein x is 2 or 3) and a film forming chemical decomposed in the range of +1.0 to 3.0 V based on an equilibrium potential between metal lithium and lithium ion.
