Hydrogel polymer electrolytes toward better zinc-ion batteries: a comprehensive review

eScience, Journal Year: 2024, Volume and Issue: unknown, P. 100294 - 100294

Published: July 1, 2024

Aqueous zinc-ion batteries (ZIBs) represent a promising solution for "beyond-lithium-ion" chemistries, but certain problems hinder their further development, especially when conventional aqueous electrolytes are involved. Hydrogel polymer (HPEs) offer opportunities to circumvent these issues. This review aims provide fundamental understanding of how design better HPEs high-performing ZIBs, through critically analyzing the recent literature. Concerns regarding HPEs' mechanical, interfacial, and electrochemical characteristics addressed, followed by in-depth insights into underlying mechanisms. Possibilities practical applications also discussed.

Published: April 22, 2024

Aqueous zinc-ion hybrid supercapacitors (ZHSCs) have attracted considerable attention because they are inexpensive and safe. However, the inadequate energy densities, power cycling performance of current ZHSC energy-storage devices impediments that need to be overcome enable further development commercialization this technology. To address these issues, in study, we prepared carbon-based ZHSCs using a series porous carbon materials derived from Sanhua liquor lees (SLPCs). Among them, best was observed for SLPC-A13, which exhibited excellent properties high-surface-area structure (2667 m2 g–1) with abundant micropores. The Zn//SLPC-A13 device assembled by 2 mol L–1 ZnSO4, Zn foil as electrolyte, cathode, anode, respectively. delivered an ultrahigh density 137 Wh kg–1 at 462 W kg–1. Remarkably, retained 100% its specific capacitance after 120,000 cycles long-term charge/discharge testing, 62% 250,000 cycles. This outstanding is primarily attributed SLPC-A13 material, promotes rapid adsorption desorption ions, charge–discharge process, roughens anode manner improves reversible Zn-ion plating/stripping efficiency. study provides ideas preparation cathode materials.
