ABSTRACT:
The non-aqueous electrolyte secondary battery of the present invention includes a positive electrode containing a lithium-containing transition metal oxide as a positive electrode active material, a negative electrode, a separator interposed between the positive electrode and the negative electrode and a non-aqueous electrolyte. The non-aqueous electrolyte includes a non-aqueous solvent and a solute dissolved therein, and the non-aqueous solvent includes a solvent having an electron-withdrawing substituent. The solvent having an electron-withdrawing substituent includes at least one selected from the group consisting of a sulfonic solvent, a nitrile solvent, a ketonic solvent, a fluorine-containing solvent, a chlorine-containing solvent and a carboxylic acid ester solvent. The separator includes a material containing an electron-withdrawing substituent or an atom having an unshared electron pair.
