Advanced Eutectogel Electrolyte for High-Performance and Wide-Temperature Flexible Zinc-Air Batteries.

Despite ongoing challenges, achieving further breakthroughs in the development of gel polymer electrolytes with a wide temperature range, excellent liquid retention capability and enhanced anode compatibility in flexible zinc-air batteries (FZABs) remains a significant objective. This study presents a significant advancement in the development of choline chloride/ethylene glycol-polyvinyl alcohol (ChCl/EG-PVA) eutectogel electrolyte, tailored for high-performance operation across a wide temperature range. Systematic in-situ and ex-situ characterizations and theoretical simulations confirm the formation of robust hydrogen bonding and denser polymer cross-linked networks within the prepared eutectogel, leading to enhanced liquid retention ability (93.

Use of Fe-HBTC and GO Compounds To Prepare N/Fe-Doped Carbon for a High-Performance Oxygen Reduction Reaction Catalyst.

Zinc-air batteries (ZABs), as a new type of energy storage and conversion device, have received lots of attention due to their high energy density and low cost. The electrode material is a key factor for improving the performance of ZABs. Here, a facile strategy for the fabrication of N-rich porous carbon is reported.
