Abstract: Energy storage devices, battery cells, and rechargeable batteries of the present technology may include an anode and a cathode. The battery cells may include a separator positioned between the anode and the cathode. The battery cells may include an electrolyte incorporated with the anode and the cathode. The battery cells may also include a pseudo-reference electrode at least partially in contact with the electrolyte. The pseudo-reference electrode may be positioned between layers of the separator.

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 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 first 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 may extend from the cathode current collector in a direction normal to a direction the anode tab extends from the anode current collector. The cathode tab may be electrically coupled with a busbar disposed within the housing.
