Original Abstract Submitted
A lithium primary battery includes an outer can, a wound-electrode assembly, and a non-aqueous electrolyte. The wound-electrode assembly includes a positive electrode, a negative electrode, and a separator which are provided between the electrodes and are wound together. The positive electrode contains manganese dioxide. The negative electrode contains at least one substance selected from the group consisting of metallic lithium and metallic lithium containing a lithium alloy, and has a first main surface and a second main surface opposite to the first main surface. The first main surface and an entirety of the second main surface of the negative electrode face the positive electrode. The total area S of the first main surface and the second main surface of the negative electrode satisfies 250 cm≤S≤700 cm. The thickness Tp of the positive electrode satisfies 0.8 mm≤Tp≤1.4 mm. The outer diameter D of the outer can satisfies 25 mm≤D≤37 mm. The distance C between the outer can and the wound-electrode assembly satisfies 0.3 mm≤C≤1.0 mm.
