A Janus Separator Regulating Zinc Deposition Behavior Synergistically by Cellulose and ZrO2 Nanoparticles Toward High‐Performance Aqueous Zinc‐Ion Batteries

Aqueous zinc-ion batteries (AZIBs) stand out among many energy storage systems due to their many merits, and it's expected to become an alternative to the prevailing alkali metal ion batteries. Nevertheless, the cumbersome manufacturing process and the high cost of conventional separators make them unfavorable for large-scale applications. Herein, inspired by the unique nature of cellulose and ZrO
