Non-aqueous electrolyte secondary cell

A non-aqueous electrolyte secondary cell having high temperature storage characteristics and cycle characteristics is provided. This object is realized by adopting the following configuration. The non-aqueous electrolyte secondary cell includes a positive electrode having a positive electrode active material a negative electrode having a negative electrode active material and a non-aqueous electrolyte having a non-aqueous solvent and an electrolyte salt. And the positive electrode active material contains a compound represented by Li a (Ni b Co c Mn d ) 1-x-y W x Zr y O 2 (0.9‰¤a‰¤1.2, 0.3‰¤b‰¤0.6, 0.1‰¤c‰¤0.7, 0‰¤d‰¤0.4, b+c+d=1, 0.001‰¤x‰¤0.05, 0.001‰¤y‰¤0.05); and the non-aqueous electrolyte contains at least one compound selected from the group consisting of cyclohexylbenzene, tert-butylbenzene and tert-amylbenzene in a total concentration of 0.1 to 5% by mass relative to the mass of the non-aqueous electrolyte.
