摘要： A dual electrolyte battery comprises a cathode, an anode, a catholyte in contact with the cathode, and an anolyte in contact with the anode. The catholyte comprises a first gelled electrolyte solution, and the anolyte comprises a second gelled electrolyte solution. A concentration of an electrolyte in the anolyte is higher than a concentration of the electrolyte in the catholyte.

摘要： A membraneless battery comprising a cathode comprising a cathode electroactive material; an anode comprising an anode electroactive material; a catholyte in contact with the cathode, wherein the catholyte is not in contact with the anode; an anolyte in contact with the anode, wherein the anolyte is not in contact with the cathode; and one or more buffer interlayers disposed between the anolyte and the catholyte. The catholyte has a pH of less than 4, and the anolyte has a pH of greater than 10. The one or more buffer interlayers regulate a pH in the battery. The anode electroactive material comprises a Zn electroactive material. At least one of the one or more buffer interlayers comprises a weak acid and its conjugate base; and/or at least one of the one or more buffer interlayers comprises a weak base and its conjugate acid.

摘要： A battery comprises an anode, a cathode, and a polymer electrolyte disposed between the anode and the cathode. The polymer electrolyte can include an inert hydrophilic polymer matrix impregnated with an aqueous electrolyte. The hydrophilic polymer matrix can include a polar vinyl monomer, an initiator, and a cross-linker. A gassing inhibitor can be included in the polymer electrolyte to help avoid issues with overcharging of the electrodes.
