Synergistic Dual-Plasticizer Engineering of Gel Polymer Electrolytes for Accelerated Zn²⁺ Transport and Stable Zinc Deposition
This study introduces a synergistic dual-plasticizer strategy incorporating propylene carbonate and glycerol into a citric acid-crosslinked carboxymethyl cellulose gel polymer electrolyte, which simultaneously enhances ionic conductivity and Zn²⁺ transference number to achieve stable zinc deposition and durable performance in aqueous zinc-ion batteries.
