Abstract
A rechargeable alkaline battery includes an anode comprising zinc, a cathode, and separator disposed between the anode and the cathode. The separator comprises a water-insoluble metal hydroxide. For example, the water-insoluble metal hydroxide can be magnesium hydroxide, calcium hydroxide, strontium hydroxide, barium hydroxide, or any combination thereof. The separator comprising the water-insoluble metal hydroxide can serve to capture a portion of any zincate ions produced at the anode prior to the zincate ions passing through the separator to the cathode.
