Aspartame Endowed ZnO-Based Self-Healing Solid Electrolyte Interface Film for Long-Cycling and Wide-Temperature Aqueous Zn-Ion Batteries
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−1capacity after 1,750 cycles in NH4+-V2O5full cells.

A groundbreaking study published in Nano-Micro Letters presents a novel approach to optimizing the stability and performance of zinc anodes in aqueous zinc-ion batteries (AZIBs) by developing a self-healing ZnO-based solid electrolyte interphase (SEI) film. Led by Professor Jingjing Tang and Juan Yang from Central South University, the research team introduced aspartame (APM) as an electrolyte additive to enhance the corrosion resistance and cycling stability of zinc anodes.
