Abstract Proton insertion mechanism with fast reaction kinetics is attracting more and attention for high‐rate durable aqueous Zn─MnO 2 batteries. However, hydrated Zn 2+ accompanied Jahn–Teller effect Mn 3+ disproportionation generally leads to sluggish rate capability irreversible structure transformation. Here, carboxyl‐carbon nanotubes supported α‐MnO nanoarrays (C─MnO ) cathode successfully fabricated by a convent grinding process high‐performance Specifically, the (CNTs) skeleton endows shorter ion diffusion route active sites proton adsorption, benefiting electron transport reversible evolution of MnO . More importantly, electronegative carboxyl groups Mn─O─C interfacial bonds can effectively restrain dissolution shuttle improved structural integrity redox reactivity. Consequently, C─MnO exhibits high capacity, superior capability, outstanding cycling stability over 10 000 cycles. Even at ultra‐high mass loading (20 mg cm −2 ), Zn//C─MnO punch cell displays excellent capacity (202 mAh) 94.5% retention after 114 cycles, providing new insights practical application advanced Zn‐Mn

Conductive Metal–Organic Frameworks Anchoring on V₃O₇·H₂O Nanobelts Toward High‐Capacity and Long‐Life Zinc‐Ion Batteries

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Апрель 25, 2025

Abstract Layered vanadium oxides, characteristic of multi‐electron redox reactions, have significantly expanded the achievable practical capacity in zinc‐ion batteries. However, low electrical conductivity and sluggish reaction kinetics still hinder their applications. Herein, anchoring strategy is demonstrated through conductive metal–organic frameworks composed Cu ligands hexahydroxytriphenylene (Cu‐HHTP) anchored on V 3 O 7 ·H 2 nanobelts via π ‐d conjugation interaction. The resulting Cu‐HHTP remarkably enhances nanobelts, provides fast efficient Zn 2+ store sites. as‐assembled batteries Zn||VO@Cu‐HHTP‐2 possess a specific 518 mAh g −1 at 0.2 A . They achieve 5000 times cycling life with high retention rate 81% 10 Furthermore, pouch keep charge discharge time 3700 s under violent deformation. Therefore, it believed that this reliable fabrication will pave way for high‐performance zinc ion
