Abstract
A non-aqueous electrolyte battery is disclosed. The non-aqueous electrolyte battery include a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. The negative electrode includes an anode mixture layer having a volume density of 1.70 to 1.90 g/cm3 prior to being subjected to charge and discharge processes. 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.
