An alternative grid energy storage system is described herein. In one embodiment, an electrochemical cell comprises a high specific surface area cathode (e.g., a cathode comprising a carbon nanofoam paper, a carbon nanotube mesh, a particulate carbon material, electrolytic manganese dioxide, or a manganese dioxide film), a zinc or lead anode (e.g., Zn or Pb foil), a selective ion-conductive separator that does not conduct zinc ions (e.g., a NAFION sulfonated tetrafluoroethylene based fluoropolymer-copolymer separator) between the anode and the cathode, and an aqueous electrolyte comprising a manganese salt (e.g., aqueous manganese sulfate) contacting the electrodes and the separator. A battery comprising two or more of the electrochemical cells electrically connected together in series, parallel, or both, also is described.
An aqueous manganese ion electrochemical cell comprising a high specific surface area cathode, an anode, a selective ion-conductive separator between the anode and the cathode, and an aqueous electrolyte comprising a manganese salt contacting the anode, the cathode, and the separator;
An aqueous manganese ion electrochemical cell comprises a cathode, an anode, a selective ion-conductive separator between the anode and the cathode, and an aqueous electrolyte comprising a manganese salt contacting the anode, the cathode, and the separator;
