Zusammenfassung: | A lithium primary battery including a battery case, an electrode group housed in the battery case, and a non-aqueous electrolyte. The non-aqueous electrolyte contains a non-aqueous solvent, a solute, and an additive. The electrode group includes a positive electrode, a negative electrode, and a separator interposed therebetween. The negative electrode includes a metal lithium or lithium alloy foil, and has a shape having a longitudinal direction and a lateral direction, with a long tape attached to at least one principal surface of the negative electrode along the longitudinal direction. The tape includes a resin base material and an adhesive layer, and has a width of 0.5 mm to 3 mm. The additive includes a phosphorus compound having a POn structure having a phosphorus atom and n oxygen atoms bonded to the phosphorus atom, where n=3 or 4. |
