NOVELTY - A non-aqueous electrolyte battery (E) comprises a positive electrode including a positive electrode layer formed on at least one surface of a positive electrode collector, a negative electrode including a negative electrode layer formed on at least one surface of a negative electrode collector, a separator disposed between the positive and negative electrode, and a non-aqueous electrolyte containing a lithium salt.    USE - For powering electrical equipment such as electric vehicle including an electric bicycle, electric motorcycle, and electric automobile (claimed).    ADVANTAGE - The non-aqueous electrolyte battery has improved cycle life due to protected positive electrode from overcharge, suppressed elution of positive electrode, and suppressed capacity deterioration in cycles of positive electrode.    DETAILED DESCRIPTION - A non-aqueous electrolyte battery (E) comprises a positive electrode including a positive electrode layer formed on at least one surface of a positive electrode collector, a negative electrode including a negative electrode layer formed on at least one surface of a negative electrode collector, a separator disposed between the positive and negative electrode, and a non-aqueous electrolyte containing a lithium salt. The negative electrode layer contains a negative electrode active material which can insert and release lithium ions at greater than or equal to 0.4 V (V.S. Li/Li+), the lithium salt contains LiPF6 with a concentration of less than 50% (including 0%), and the formulae 1 less than or equal to Q2/Q1 (I) and C'/A'=1-2 (II) are satisfied, where portion facing the positive electrode through the separator of the negative electrode layer is a facing portion of the negative electrode, and portion facing the negative electrode through the separator of the positive electrode layer is a facing portion of the positive electrode.    Q1=capacitance in the facing portion of the negative electrode;    Q2=capacitance in the facing portion of the positive electrode;    A'=area of a surface including the facing portion of the negative electrode of the negative electrode layer;    C'=area of a surface including the facing portion of the positive electrode of the positive electrode layer.    INDEPENDENT CLAIMS are included for the following:    (1) manufacturing (M1) non-aqueous electrolyte battery (E) involving providing a positive electrode including positive electrode layer formed on positive electrode collector surface, providing a negative electrode including negative electrode layer formed on negative electrode collector surface, providing a separator disposed between the positive and negative electrode, and providing a non-aqueous electrolyte containing lithium salt; and    (2) method for powering electrical equipment (M2) involving electrically connecting the non-aqueous electrolyte battery (E) to an electric vehicle.
