This study introduces a method of using glucose as an electrolyte additive to improve the performance of aqueous Zn-ion batteries, enabling the zinc anode to have higher reversibility and stability.
Aqueous Zn-ion batteries (ZIBs) featuring safety, affordability and high energy density may provide a promising solution to the demand for better energy storage devices. ZIBs with high electrochemical performances rely on a stable and reversible Zn metal negative electrode. The side reactions such as the hydrogen evolution reaction (HER) at the anode-electrolyte interface are responsible for the low reversibility, and uneven Zn deposition/dissolution gives rise to the instability of Zn anode. Here, a facile and scalable method of regulating electrolytes has been proposed by Chao and his co-works through adding a lowcost, safe and environmentally-friendly electrolyte additive: glucose. Theoretical calculations and experimental studies reveal that the glucose not only suppresses side reactions by modulating the solvated shell of Zn2+ but also homogenizes Zn deposition/dissolution through forming a special local absorption interface. This bi-functional electrolyte additive endows the Zn anode with both high reversibility and stability, which efficiently improves the performances of ZIBs. This work explores a promising electrolyte strategy for realizing the large-scale application of ZIBs.
