Zinc composite anode for batteries with solid electrolyte

γ-MnO2 Synthesized from Raw Ore for Protonic Solid-Battery

“…A complete solid-state cell using hexauranyl phosphate acid (HUP), as a solid-state proton conducting electrolyte, and MnO 2 or PbO 2 , as a cathode, has been reported earlier (9,10). In both the cases, the results obtained in terms of open circuit voltage and discharge characteristics were encouraging.…”

“…The applicability of sodium thiosulphate, as a room-temperature proton conductor in battery has been discussed elsewhere (14). Composite zinc anode (Zn-composite) was prepared following the procedure described by Tedjar et al (15). Appropriate amount of solid electrolyte in Zinc-composite was mixed for better proton exchange between the composite electrode and electrolyte (7).…”

“…As a matter of fact, in protonic secondary batteries, the electrolyte should be stable, and the protons supplied by the anode must be transferred via the ionic phase for cathodic insertion (8). A complete solid-state cell using hexauranyl phosphate acid (HUP), as a solid-state proton conducting electrolyte, and MnO 2 or PbO 2 , as a cathode, has been reported earlier (9,10). In both the cases, the results obtained in terms of open circuit voltage and discharge characteristics were encouraging.…”

Protonic batteries based on chemically synthesized MnO2

“…Practically, composite zinc anode was prepared following the procedure described by Tedjar et al [7]. Proton-conducting solid electrolyte was Zn-exchanged montmorillonite (Zn-Mt) in the form of a thin layer.…”

“…As a matter fact, a considerable amount of work has been focused on the development of room-temperature proton conductors as solid electrolytes and composite anode material that acts as a proton reservoir [4][5][6][7][8][9]. On the other hand, cathode material has relatively less attended.…”
