Zinc polymer electrolytes in battery systems

Ambient temperature, zinc ion-conducting, binary molten electrolyte based on acetamide and zinc perchlorate: Application in rechargeable zinc batteries

“…The conductivity of such electrolytes does not exceed lS cm À1 under ambient conditions. Aprotic solvents such as ethylene carbonate (EC), propylene carbonate (PC), and dimethyl sulfoxide (DMSO) containing polymer electrolytes have been reported [15][16][17][18][19][20] from a few laboratories. Zn ionconducting polymeric gel electrolytes [17,18] using zinc triflate with EC and PC in polymeric matrixes such as poly(vinylidenefluoride) (PVDF) or poly(acrylonitrile) (PAN) possess [17,18] conductivities in the range of 2.6 and 3.94 mS cm À1 , respectively, at 298 K. The disadvantages in using polymer/gel polymer electrolytes in rechargeable secondary batteries are poor ambient temperature ionic conductivity (due to low solubility of zinc salts), flammability, and volatility of organic solvent such as ethylene carbonate and propylene carbonate, leading to vapor pressure buildup, etc.…”

Rechargeable Aqueous Zinc‐Ion Batteries with Mild Electrolytes: A Comprehensive Review

“…The Mn loss stems from the disproportionation reactions of the discharged product (MnOOH) in weak acidic electrolytes, which can be described as [Eq. (17)]: [201] 2MnOOH…”

All-solid secondary polyaniline-zinc battery

“…Fauvarque et al used a PEO-KOH based electrolyte in a solid state zinc-nickel battery [8]. Hagan et al used a solid polymer electrolyte (PEO n -ZnX 2 ) in a zinc battery [9].…”

“…Scrosati [4] reported that the addition of inert fillers to the electrolytes increased the conductivity. PEO-based electrolytes have been utilized in solid state zinc batteries [8,9]. Fauvarque et al used a PEO-KOH based electrolyte in a solid state zinc-nickel battery [8].…”
