Abstract Electrolyte additives (EAs) are cost‐effective for stabilization of lithium metal batteries (LMBs). Nevertheless, most EAs gradually consumed during the deposition process, rendering them inadequate long‐term cyclability. Herein, a novel hybrid metal–organic framework (MOF)‐based non‐expendable additive is prepared through polymerization pentaerythritol tetraacrylate (PETEA) on zeolitic imidazolate (ZIF‐67). Owing to partial coating by PETEA‐based polymer, exposed unsaturated sites ZIF‐67 still attenuate interaction between ions (Li + ) and anions, enabling rapid electrochemical kinetics uniform Li deposition. Concurrently, polymerized PETEA partially enters solvation sheath expels some organic solvents Van der Waals interactions, which promotes derivation an inorganic‐rich SEI inhibits dendrite formation. Accordingly, this additive‐contained Li||Li symmetric cell exhibits stability over 1200 h with small overpotential 75 mV. Additionally, assembled Li||LiFePO 4 full cells negative/positive ratio 1.76 delivers stable cyclability 400 cycles at 0.5 C. Moreover, Li||LiNi 0.8 Mn 0.1 Co O 2 high‐voltage displays impressive capacity retention 80% 311 This study provides valuable guidance design multifunctional advancing high‐performance LMBs.

Potassium metal batteries (KMBs) hold promise for stationary energy storage with certain cost and resource merits. Nevertheless, their practicability is greatly handicapped by dendrite-related anodes, the target design of specialized separators to boost anode safety in its nascent stage. Here, we develop a thermally robust biopolymeric separator customized via solvent-exchange amino-siloxane decoration strategy render durable safe KMBs. Through experimental investigation theoretical computation, reveal that optimized porosity surface functionalization could manage ion transport interfacial chemistry, thereby enabling efficient K+ diffusion favorable solid electrolyte interphase achieve prolonged cycling stability (over 3000 h). The thus-assembled full cell retains 80% initial capacity after 400 cycles at 0.5 A g–1. heat-proof property designed further demonstrated. Our separator, affording multifunctional features, provides an appealing solution circumvent instability issues associated potassium batteries.
