Description
Summary:Highlights Aspartame additive in electrolyte enables the in situ formation of ZnO-based solid electrolyte interphase, enhancing Zn anode corrosion resistance and stability with excellent self-healing capabilities. Zn║Zn symmetric cells with APM-modified electrolyte operate stably for 6,400 h at − 5 °C, 10,330 h at 25 °C, and 2,250 h at 40 °C, with a high DOD of 85.2%. Achieves 99.59% Coulombic efficiency, suppresses dendrite growth, and maintains 150 mAh g−1 capacity after 1,750 cycles in NH4+-V2O5 full cells.
