This research demonstrates enhanced stability of zinc metal anodes in aqueous zinc-ion batteries, suggesting molecular engineering may mitigate corrosion.
Key Points
To investigate the impact of molecular engineering on zinc metal anodes in aqueous zinc-ion batteries.
Utilized bis ( 2 ‐carboxyethyl) disulfide as electrolyte additive
Analyzed the solvation structure and hydrogen-bond network
Examined performance in Zn||Zn symmetric cells and Zn||VO2 full cells
Achieved stable stripping/plating behavior for over 4700 hours at 1 mA cm−2
Maintained 79.5% capacity retention after 5000 cycles at 5 A g−1
Effectively suppressed corrosion and side reactions in zinc anodes
