Abstract: Batteries according to embodiments of the present technology may include a housing including a first terminal disposed on a first side of the housing and a second terminal disposed on the first side of the housing. The batteries may include an electrode stack positioned within the housing. The electrode stack may include an anode current collector. The anode current collector may define an anode tab along a second side of the anode current collector, and be electrically coupled with the first terminal. The electrode stack may include a cathode current collector. The cathode current collector may define a cathode tab along a second side of the cathode current collector. The cathode tab and anode tab may extend in a direction normal to a direction facing the first side of the housing. The cathode tab may be electrically coupled with the second terminal.

Abstract: Batteries are described that include a cathode material, and anode material, and a polymeric material that separates the cathode material from the anode material. The polymeric material has hydroxide ion conductivity of at least about 50 mS/cm, and a diffusion ration of hydroxide ions to at least one type of metal ion of at least about 10:1. Also described are methods of making a battery that include forming a layer of polymeric material between a first electrode and second electrode of the battery. In additional methods, the polymeric material is coated on at least one of the electrodes of the battery. In further methods, the polymeric material is admixed with at least one of the electrode materials to make a composite electrode material that is incorporated into the electrode.

Abstract: Batteries are described that include a cathode, an anode, and a separator that electrically insulates the cathode from the anode. The separator includes a cation exchange membrane positioned between a first anion exchange membrane and a second anion exchange membrane, and has a hydroxide ion conductivity of at least about 10 mS/cm, and a diffusion ratio of hydroxide ions to at least one type of metal ion of at least about 100:1. Also described are methods of making a battery that include forming a separator between a cathode electrode and an anode electrode. The separator includes a cation exchange membrane positioned between a first anion exchange membrane and a second anion exchange membrane. The methods also include contacting the cathode electrode with a cathode current collector and the anode electrode with an anode current collector, where the cathode and anode currently collectors are electrically insulated from each other by a spacer material.
