ABSTRACT:
A non-aqueous electrolyte battery includes an cathode having an cathode mixture layer containing an cathode active material; an anode having an anode mixture layer containing an anode active material which includes a first active material and/or a second active material, where the first active material includes a metal, alloy or compound capable of react with lithium, and the second active material includes a carbonaceous material; and a non-aqueous electrolytic solution. By allowing the anode to contain the first active material in a predetermined amount, and by controlling the packing ratio of the anode mixture layer, the anode is successfully prevented from being degraded due to expansion-and-shrinkage of the anode active material in response to the charge/discharge cycle, and thus degradation of the charge/discharge characteristics of the battery is suppressed.
