    摘要: The disclosure describes a non-aqueous electrolyte battery with an improved cycle life. The non-aqueous electrolyte battery includes a positive electrode including a positive electrode layer, a negative electrode including a negative electrode layer, a separator disposed between the positive electrode and the negative electrode, and a non-aqueous electrolyte containing a lithium salt. The negative electrode layer may contain a negative electrode active material which can insert and release lithium ions at 0.4 V or more (V.S. Li/Li+). The lithium salt may contains LiPF6 with a concentration of less than 50% (including 0%). The non-aqueous electrolyte battery may meet the following two formulas: 1≦Q2/Q1 (I) and 1≦C/A≦2 (II), where Q1 represents a capacitance in a facing portion of the negative electrode, Q2 represents a capacitance in the facing portion of the positive electrode, A represents an area of a surface including the facing portion of the negative electrode of the negative electrode layer, and C represents an area of a surface including the facing portion of the positive electrode of the positive electrode layer.
