ACS Nano, Journal Year: 2023, Volume and Issue: 17(12), P. 11946 - 11956

Published: June 15, 2023

Dendrite growth and electrode/electrolyte interface side reactions in aqueous zinc-ion batteries (AZIBs) not only impair the battery lifetime but also pose serious safety concerns for system, hindering its application large-scale energy storage systems. Herein, by introducing positively charged chlorinated graphene quantum dot (Cl-GQD) additives into electrolyte, a bifunctional dynamic adaptive interphase is proposed to achieve Zn deposition regulation reaction suppression AZIBs. During charging process, Cl-GQDs are adsorbed onto surface, acting as an electrostatic shield layer that facilitates smooth deposition. In addition, relative hydrophobic properties of groups build protective anode, mitigating corrosion anode water molecules. More importantly, consumed throughout cell operation exhibit reconfiguration behavior, which ensures stability sustainability this interphase. Consequently, cells mediated enable dendrite-free plating/stripping more than 2000 h. Particularly, even at 45.5% depth discharge, modified Zn//LiMn2O4 hybrid still retain 86% capacity retention after 100 cycles, confirming feasibility simple approach with limited sources.
