Lithium-ion battery (LIB) now constitutes the paramount way to store energy technology. However, due to several inherent limitations, rechargeable zinc-ion batteries (RZIBs) have emerged as a promising alternative, offering advantages such as enhanced safety, low cost, abundant raw materials, and environmental friendliness.

摘要

Lithium-ion battery (LIB) now constitutes the paramount way to store energy technology. However, due to several inherent limitations, rechargeable zinc-ion batteries (RZIBs) have emerged as a promising alternative, offering advantages such as enhanced safety, low cost, abundant raw materials, and environmental friendliness. Nevertheless, zinc metal anodes in aqueous systems possess significant disadvantages, including dendrite formation, hydrogen gas, ZnO passive layers, and zinc corrosion. To address these issues, a polyacrylamide/gelatin (PAM/gelatin)-based quasi-solid electrolytes (QSE) has been developed. PAM is an effective QSE matrix because to its exceptional electrochemical stability and flexibility; nevertheless, the incorporation of gelatin enhances ionic transport efficiency. In addition, Zn symmetric cell incorporating PAM/gelatin QSE reveals reduced overpotential, prolonged stability during Zn symmetric plating/stripping cycles, and along with improved ionic conductivity relative to the PAM QSE. Zinc-MnO2 battery together with PAM and PAM/gelatin QSE is also evaluated, achieving the specific capacities of 75 and 123 mAh g−1, respectively.
