Patent ID: 7989108

Claim:
A non-aqueous electrolyte battery comprising a positive electrode, a negative electrode, and a non-aqueous electrolyte, wherein said negative electrode includes a molded body made by compression molding a granulated material including a negative electrode active material, a conductive agent, and a binder, said negative electrode active material includes a Si-containing material, wherein a volume-based 90% particle size R (D 90 ) of said negative electrode active material, a volume-based 10% particle size R z (D 10 ) and a volume based 90% particle size R z (D 90 ) of said granulated material, and a thickness T of the molded body, satisfies the following relationship formulae: R ( D 90 )< Rz ( D 10 ), (i) Rz ( D 90 )< T, (ii) 34 μm≦ Rz ( D 10 )≦126 μm, and (iii) 128 μm≦ Rz ( D 90 )≦285 μm, and (iv) an electric conductivity of said granulated material is 0.05 S/cm or more when a density of said granulated material is 0.9 g/cm 3 .
