Abstract
This negative electrode for a zinc battery comprises a nonporous current collector and a negative electrode mixture layer which is held by the current collector and contains at least one of zinc, a zinc alloy, and a zinc-containing compound. The negative electrode has a current collector-exposed section in which the negative electrode mixture layer is not disposed, in a portion located at the outermost circumferential surface when wound.
Claims6
A negative electrode for a zinc battery, the negative electrode being wound with a positive electrode in a stacked state with a separator therebetween, and housed within an outer can, the negative electrode comprising:
- a current collector that is non-porous;
- and
- a negative electrode mixture layer held by the current collector and containing at least one of zinc, a zinc alloy, and a zinc-containing compound,
- wherein
- the negative electrode includes, in a portion thereof that is located at an outermost peripheral surface when the negative electrode is wound, a current collector exposed portion where the negative electrode mixture layer is not disposed and the current collector is exposed.
