A co-solvent in aqueous electrolyte towards ultralong-life rechargeable zinc-ion batteries

Zezhuo Li et al.

Summary: Regulating the Zn2+ solvation structure by introducing a polar solvent TMU in the aqueous electrolyte can solve the issues of Zn dendrite and H-2 evolution reaction. The strong interactions between TMU and Zn2+ interrupt the intrinsic hydrogen-bonds of H2O, reducing its activity and suppressing Zn dendrite and HER. With TMU-based electrolyte, Zn||Cu cells can cycle for over 6000 cycles with high Columbic efficiency, and Zn||Zn cells achieve a cumulative capacity exceeding most reported works. Our work highlights the importance of molecular-level design in stabilizing the Zn anode and achieving high-performance AZIBs.

Stable Zn Metal Anodes Enabled by Restricted Self-Diffusion Via Succinimide Surfactant

Haoliang Wang et al.

Summary: Introduced a surfactant of succinimide (SI) that occupies the compact region of the electrical double layer (EDL) at the Zn/electrolyte interface, protecting Zn surface from corrosion in aqueous electrolytes. SI surfactants restrict the self-diffusion of Zn adatoms and tune interfacial reaction kinetics, promoting small and dense nuclei instead of large Zn dendrites. SI enables high Coulombic efficiency and long-term cycling stability in Zn-VS2 batteries.
