Patent ID: 8415053

Claim:
A nonaqueous electrolyte battery comprising: a positive electrode; a negative electrode comprising a current collector made of aluminum or an aluminum alloy and an active material layer laminated on the current collector, the active material layer containing first active material particles that have an average particle diameter of 1 μm or less and are represented by Li 4+x Ti 5 O 12 (0≦x≦3) and second active material particles represented by Li 4+x Ti 5 O 12 (0≦x≦3), MnO 2 , FeS, FeS 2 , CuO, Cu 4 O(PO 4 ) 2 , MoO 3 or TiO 2 and having an average particle diameter of 2 to 50 μm, and a true density of the second active material particles being larger by 0.01 to 2.5 g/cm 3 than a true density of the first active material particles; and a nonaqueous electrolyte.
