Ethylene Carbonate as an Electrolyte Additive for Performance Stabilization in Aqueous Zinc Metal Batteries

Li M, et al. Journal of Physics and Chemistry of Solids, 2026, 212, 113558.

This case study reports the experimental application of ethylene carbonate (EC) as an electrolyte additive to enhance the electrochemical stability of aqueous zinc metal batteries. Zinc symmetric and full cells were assembled in CR2032 coin-type configurations using glass fiber separators and a baseline electrolyte of 2 M ZnSO₄, with EC introduced at a concentration of 0.7 M. Zinc foil served as the anode, while the cathode was prepared by casting a slurry of V₂O₅, acetylene black, and polyvinylidene fluoride (7:2:1, w/w) onto stainless steel foil, followed by drying at 60 °C for 10 h. Electrochemical performance was evaluated via cyclic voltammetry using a CHI660E workstation and galvanostatic charge-discharge testing on a LAND CT2001A system. The incorporation of EC effectively modulated the electrolyte hydrogen-bonding network, reduced water activity, and suppressed hydrogen evolution-induced corrosion, enabling stable Zn symmetric cell cycling for over 920 h and full-cell durability exceeding 2500 cycles, demonstrating the practical applicability of EC-based electrolyte engineering.
