[PROBLEMS] To provide a non-aqueous electrolyte battery having high capacity, excellent cycle life and high safety, and a method for manufacturing the same. A nonaqueous electrolyte battery includes a polar group containing at least one of a hydroxyl group, a silanol group, and a carboxyl group, and a separator in which at least a part of the polar group is lithiated. Between a negative electrode and a positive electrode, a separator containing at least one of a polar group of a hydroxyl group, a silanol group, and a carboxyl group is interposed, and is housed in a battery can in this state, and an electrolytic solution is injected into the battery can. A method for producing a non-aqueous electrolyte battery, in which at least a part of the polar groups contained is lithiated before assembling the non-aqueous electrolyte battery. |
