  • SAFE AND FLEXIBLE CHITOSAN-BASED GEL ELECTROLYTE IN RECHARGEABLE ZINC ELECTROLYTIC MANGANESE DIOXIDE (EMD) ALKALINE BATTERIES
    Publication number: 20240154163
    Abstract: Zinc electrolytic manganese dioxide (EMD) batteries including a high performing flexible chitosan-based gel electrolyte with poly-vinyl alcohol (PVA) and potassium hydroxide (KOH) additives were prepared. The Zn-EMD batteries were constructed using an optimized assembly technique employed to achieve good interfacial contact between the layers. Attaining energy densities between 150-250 Wh/kg (w.r.t cathode mass) is possible for these batteries, encouraging their use in wearable or flexible electronics. Using the chitosan-based gel electrolyte and limited voltage window testing, the prepared Zn-EMD alkaline batteries are among the best reported polymer-based alkaline electrolyte Zn rechargeable batteries.
