Aqueous battery current collectors

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/cm.sup.2. 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.
