Solid-state polymer electrolytes (SPEs) are promising for high-performance zinc metal batteries (ZMBs), but they encounter critical challenges of low ionic conductivity, limited Zn2+ transference number (tZn2+), and an unstable electrolyte-electrode interface. Here, we present effective approach involving a missing-linker metallic organic framework (MOF)-catalyzed poly(ethylene glycol) diacrylate (PEGDA)/polyacrylamide (PAM) copolymer SPE single conduction seamless contact. The single-Zn2+ is facilitated by the anchoring OTF– anions onto unsaturated sites MOF, while PEGDA PAM chains in competitive coordination with ions promote rapid Zn ion transport. Our all-solid-state electrolyte simultaneously achieves superior conductivity 1.52 mS cm–1 high tZn2+ 0.83 at room temperature, alongside uniform deposition (1000 cycles symmetric cells) plating/striping efficiencies (>99% after 600 asymmetric cells). Applications our Zn//VO2 full cells further demonstrated long lifespan 2000 extremely low-capacity degradation rate 0.012% per cycle. This work provides strategy using MOF to catalyze competitively coordinating copolymers accelerating conduction, assisting future design ZMBs.

Aqueous zinc-ion batteries (AZIBs) have experienced a rapid surge in popularity, as evident from the extensive research with over 30 000 articles published past 5 years. Previous studies on AZIBs showcased impressive long-cycle stability at high current densities, achieving thousands or tens of cycles. However, practical low densities (<1C) is restricted to merely 50-100 cycles due intensified cathode dissolution. This genuine limitation poses considerable challenge their transition laboratory industry. In this study, leveraging density functional theory (DFT) calculations, an artificial interphase that achieves both hydrophobicity and restriction outward penetration dissolved vanadium cations, thereby shifting reaction equilibrium suppressing dissolution following Le Chatelier's principle, described. The approach has resulted one best cycling stabilities date, no noticeable capacity fading after more than 200 (≈720 h) mA g

Abstract Achieving a highly robust zinc (Zn) metal anode is extremely important for improving the performance of aqueous Zn-ion batteries (AZIBs) advancing “carbon neutrality” society, which hampered by uncontrollable growth Zn dendrite and severe side reactions including hydrogen evolution reaction, corrosion, passivation, etc. Herein, an interlayer containing fluorinated zincophilic covalent organic framework with sulfonic acid groups (COF-S-F) developed on (Zn@COF-S-F) as artificial solid electrolyte interface (SEI). Sulfonic group (− SO 3 H) in COF-S-F can effectively ameliorate desolvation process hydrated ions, three-dimensional channel fluoride (-F) provide interconnected channels favorable transport ions ion-confinement effects, endowing Zn@COF-S-F dendrite-free morphology suppressed reactions. Consequently, symmetric cell stably cycle 1,000 h low average hysteresis voltage (50.5 mV) at current density 1.5 mA cm −2 . Zn@COF-S-F|MnO 2 delivers discharge specific capacity 206.8 mAh g −1 1.2 A after 800 cycles high-capacity retention (87.9%). Enlightening, building SEI metallic surface targeted design has been proved effective strategy to foster practical application high-performance AZIBs.
