WIPO Patent Application WO/2023/120537
Kind Code:
A1
Abstract:
An alkaline battery according to the present invention is provided with: a closed-bottom cylindrical case; a hollow cylindrical positive electrode in contact with the inside of the case; a negative electrode which fills the hollow interior of the positive electrode and includes a negative electrode active substance including zinc; a separator disposed between the positive electrode and the negative electrode; an alkaline electrolyte; and a sealing unit. The alkaline electrolyte is contained in the positive electrode, the negative electrode, and the separator. The sealing unit is provided with a negative electrode collector body which covers the opening in the case and is partially inserted into the negative electrode. An additive fills the space between the negative electrode and the sealing unit. The additive includes a wax component having a melting point between 60°C and 110°C, inclusive. The wax component includes at least one selected from the group consisting of an aliphatic hydrocarbon compound and an ester compound.
