ACS Nano, Journal Year: 2021, Volume and Issue: 15(11), P. 18469 - 18482

Published: Nov. 5, 2021

Flexible zinc-ion hybrid capacitors (ZIHCs) based on hydrogel electrolytes are an up-and-coming and highly promising candidate for potential large-scale energy storage due to their combined complementary advantages of zinc batteries capacitors. However, the freezing induces a sharp drop in conductivity mechanical property with tremendous compromise interfacial adhesion, thereby severely impeding low-temperature application such flexible ZIHCs. To achieve ZIHCs excellent adaptability, antifreezing self-adhesive polyzwitterionic electrolyte (PZHE) is engineered via self-catalytic nano-reinforced strategy, affording unparalleled robust together superhigh strength over broad temperature ranging from 25 -60 °C. Meanwhile, water-in-salt-type PZHE filled ZnCl2 can provide ion migration channels enhance reversibility Zn metal electrodes, thus greatly reducing side reactions extending cycling life.

Understanding H₂ Evolution Electrochemistry to Minimize Solvated Water Impact on Zinc‐Anode Performance

Advanced Materials, Journal Year: 2022, Volume and Issue: 34(45)

Published: Sept. 20, 2022

H2 evolution is the reason for poor reversibility and limited cycle stability with Zn-metal anodes, impedes practical application in aqueous zinc-ion batteries (AZIBs). Here, using a combined gas chromatography experiment computation, it demonstrated that primarily originates from solvated water, rather than free water without interaction Zn2+ . Using linear sweep voltammetry (LSV) salt electrolytes, evidenced to occur at more negative potential zinc reduction because of high overpotential against on Zn metal. The hypothesis tested and, glycine additive reduce confirmed "parasitic" side reactions are suppressed anode.
