Abstract:
There is provided a secondary zinc battery including: a unit cell including; a positive-electrode plate including a positive-electrode active material layer and a positive-electrode collector; a negative-electrode plate including a negative-electrode active material layer containing zinc and a negative-electrode collector; an LDH separator covering or wrapping around the entire negative-electrode active material layer; and an electrolytic solution. The positive-electrode collector has a positive-electrode collector tab extending from one edge of the positive-electrode active material layer, and the negative-electrode collector has a negative-electrode collector tab extending from the opposite edge of the negative-electrode active material layer and beyond a vertical edge of the LDH-like compound separator. The unit cell can thereby collects electricity from the positive-electrode collector tab and the negative-electrode collector tab that are disposed at opposite edges of the unit cell. The LDH-like compound separator has at least two continuous closed edges.
