    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: Energy storage devices, battery cells, and batteries of the present technology may include a first current collector including a material characterized by a maximum corrosion current in an aqueous electrolyte below or about 2 mA/cm2. The batteries may include a cathode material coupled with the first current collector. The batteries may include a second current collector, and may include an anode material coupled with the second current collector. The batteries may also include an aqueous electrolyte characterized by a pH greater than or about 14.

    Abstract: Energy storage devices, battery cells, and batteries of the present technology may include a first current collector and a second current collector. The batteries may include an anode material coupled with the first current collector. The batteries may include a cathode material coupled with the second current collector. The batteries may also include a separator positioned between the cathode material and the anode material. The batteries may include a hydrogen-scavenger material incorporated within the anode active material or the cathode active material. The hydrogen scavenger material may absorb or react with hydrogen at a temperature above or about 20° C.

    Abstract: A redox mediator-containing electrolyte incorporated into a battery cell is described. The redox mediator-containing electrolyte includes water, at least one hydroxide salt dissolved in the water, and at least one redox mediator incorporated into the water. The at least one redox mediator increases at least one of a rate capability or a cycle life of the battery cell by at least 10%. Also described are battery cells that may include a positive electrode, a negative electrode, and the redox mediator-containing electrolyte. The battery cells may further include an ion-selective material that diffuses hydroxide ions through the material at a faster rate than at least one of the redox mediators.

    Abstract: The disclosure is directed to an apparatus comprising a substrate and a composition disposed on the substrate. The catalyst comprises a polypropylene carbonate (PPC) and a catalyst selected from the group consisting of an acid with a pKa less than or equal to 1 in water, a phase transfer catalyst, and a metal salt. The substrate and composition can be used in insulators between batteries, for example in a battery pack.
