Nanomaterials for Zinc Batteries—Aerogels

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(3), P. 194 - 194

Published: Jan. 26, 2025

Aqueous zinc batteries, mainly including Zn-ion batteries (ZIBs) and Zn–air (ZABs), are promising energy storage systems, but challenges exist at their current stage. For instance, the anode in aqueous electrolyte is impacted by anodic dendrites, hydrogen oxygen precipitation, some other harmful side reactions, which severely affect battery’s lifespan. As for traditional cathode materials ZIBs, low electrical conductivity, slow Zn2+ ion migration, easy collapse of crystal structure during embedding migration bring challenges. Also, slower critical reduction reaction (ORR), example, ZABs shows unsatisfactory results. All these issues greatly hindered development batteries. Aerogel materials, characterized high specific surface area, unique open-pore formed nanoporous structures, excellent physicochemical properties, have a positive role modification, electrode protection, catalytic reactions This manuscript provides systematic review aerogel highlighting advancements preparation application aiming to promote future progress nanomaterials
