Abstract
A non-aqueous electrolyte battery includes an electrode group includes a positive electrode and a negative electrode disposed through a separator, and a non-aqueous electrolyte. The negative electrode comprises a current collector and a porous negative electrode layer formed on the current collector and containing a lithium compound. The porous negative electrode layer has a first peak at a pore diameter of 0.04 to 0.15 μm and a second peak at a pore diameter of 0.8 to 6 μm in the relation between the pore diameter and log differential intrusion obtained in the mercury press-in method.
