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.
