    摘要: A non-aqueous electrolyte battery comprises a negative electrode comprising a current collector, and a negative electrode layer formed on one or both surfaces of the current collector, a positive electrode, and a separator interposed between the negative electrode and the positive electrode. The negative electrode layer comprises a plurality of layers laminated each other and containing a different active material each other, the layers comprising a first layer which is contacted with the current collector and contains spinel-type lithium titanate as an active material, and a second layer which is disposed to face the separator and contains Ramsdellite-type lithium titanate or anatase-type titanium oxide as an active material.
