ACS Nano, Journal Year: 2023, Volume and Issue: 17(2), P. 1610 - 1621

Published: Jan. 3, 2023

Aqueous zinc-ion batteries (AZIBs) have attracted attention for their low cost and environmental friendliness. Unfortunately, commercialization has been hampered by several problems with dendrite growth side reactions. Herein, we select sodium tartrate (TA-Na) as a dual-functional electrolyte additive to enhance the reversibility of AZIBs. The anions are preferentially adsorbed on Zn surface, then highly nucleophilic carboxylate will coordinate Zn2+ promote desolvation [Zn(H2O)6]2+, leading uniform deposition beneficial (002) plane inhibiting reactions growth. Consequently, Zn|Zn cells show long-term cycling stability over 1500 cycles at 0.5 mA cm–2. Moreover, Ta-Na improves performance Zn||MnO2 full cells, evidenced life 1000 1 A g–1 under practical conditions limited anode (negative/positive capacity ratio 10/1) controlled (electrolyte/capacity 20 μL mAh–1).
