NOVELTY - A non-aqueous electrolyte battery comprises a negative electrode, a positive electrode and a separator interposed between the negative electrode and positive electrode. The negative electrode comprises a current collector, and a negative electrode layer formed on one or both surfaces of the current collector. The negative electrode layer comprises laminated structure of several layers, each layer containing different active material. The laminated layers comprises a layer (L1) contacted with the current collector, and a layer (L2) disposed to face the separator.    USE - Non-aqueous electrolyte battery used as power source for hybrid electric vehicles and electronic device such as digital camera.    ADVANTAGE - The battery pack comprising non-aqueous electrolyte battery has excellent cycle characteristics in high current performance.    DETAILED DESCRIPTION - A non-aqueous electrolyte battery comprises a negative electrode, a positive electrode and a separator interposed between the negative electrode and positive electrode. The negative electrode comprises a current collector, and a negative electrode layer formed on one or both surfaces of the current collector. The negative electrode layer comprises laminated structure of several layers, each layer containing different active material. The laminated layers comprises a layer (L1) contacted with the current collector, and a layer (L2) disposed to face the separator. The layer (L1) contains spinel-type lithium titanate as active material, and the layer (L2) contains Ramsdellite-type lithium titanate or anatase-type titanium oxide as active material. The current collector is formed of aluminum foil or aluminum alloy foil. The layers (L1 and L2) of negative electrode layer further contain conductive agent and binder. The positive electrode comprises a current collector and a positive electrode layer. The positive electrode layer contains composite oxides chosen from lithium manganese composite oxides, lithium nickel composite oxides, lithium cobalt composite oxides, lithium nickel cobalt composite oxides, spinel-type lithium manganese nickel composite oxides, lithium manganese cobalt composite oxides and lithium iron phosphate. The non-aqueous electrolyte of battery comprises lithium salt, and an organic solvent containing ( gamma )-butyrolactone. An INDEPENDENT CLAIM is included for battery pack.
