Abstract

The invention provides a lithium primary battery including a negative electrode 12 comprising metal lithium or a lithium alloy, a positive electrode 11 including a positive electrode active material, a separator 13 interposed between the negative electrode 12 and the positive electrode 11, and a non-aqueous electrolyte. The negative electrode 12 includes a coating layer 17 on a surface thereof facing the positive electrode 11, the coating layer containing carbon particles each having fluorine-containing fine particles on the surface thereof, for the purpose of improving both the discharge performance and the high temperature storage characteristics.
