Claim Text:
1. A non-aqueous electrolyte battery comprising: a positive electrode; a negative electrode; a film casing that encloses the non-aqueous electrolyte battery; and a separator disposed between the positive electrode and the negative electrode, wherein the negative electrode includes an anode mixture layer having a volume density of 1.70 to 1.90 g/cm wherein the anode mixture layer includes mixed particles composed of spherical graphite having an average particle size of 25 to 35 μm and non-spherical graphite having an average particle size of 8 to 22 μm, wherein the spherical graphite together with the non-spherical graphite have particle size distributions such that D10 is 5 to 11 μm, D50 is 13 to 25 μm, and D90 is 27 to 45 μm, wherein polymer compound layers are disposed between the negative electrode and the separator, and between the positive electrode and the separator, wherein the polymer compound layers are composed of a porous polymer compound retaining an electrolytic solution therein, and wherein the polymer compound layers have a bonding strength of 5 mN/mm or more with at least one of the positive and negative electrodes and the separator.
