Non-aqueous electrolyte battery and producing method thereof

90109090109010903A non-aqueous electrolyte battery of the present invention includes a positive electrode, a negative electrode, and a non-aqueous electrolyte. The negative electrode includes a molded body made by compression molding a granulated material containing a negative electrode active material, a conductive agent, and a binder. The negative electrode active material includes a Si-containing material. Volume-based 90% particle size R (D) of the negative electrode active material, volume-based 10% particle size Rz (D) and 90% particle size Rz (D) of the granulated material, and thickness T of the molded body satisfy the following relation formulae: (i) R (D)
