Manganese-based materials are considered as one of the most promising cathodes in zinc-ion batteries (ZIBs) for large-scale energy storage applications owing to their cost-effectiveness, natural availability, low toxicity, multivalent states, high operation voltage, and satisfactory capacity. However, intricate mechanisms coupled with unsatisfactory cycling stability hinder commercial applications. Previous reviews have primarily focused on optimization strategies achieving capacity fast reaction kinetics, while overlooking fluctuation lacking a systematic discussion enhance these materials. Thus, this review, manganese-based ZIBs different structures systematically elucidated summarized. Next, ZIBs, including activation, degradation, dynamic evolution whole cycle calendar comprehensively analyzed. Finally, constructive based chemistry one-electron two-electron transfers durable performance proposed.

Ion‐Sieving Effect Enabled by Sulfonation of Cellulose Separator Realizing Dendrite‐Free Zn Deposition

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(27)

Published: March 7, 2024

Abstract Aqueous zinc‐ion batteries (AZIBs) hold great potential for grid‐scale energy storage systems, owing to their intrinsic safety and low cost. Nevertheless, industrialization faces challenges of severe Zn dendrites parasitic reactions. In this study, sulfonated cellulose separator (denoted as CF‐SO 3 ) with thickness, exceptional mechanical strength, large ionic conductivity is developed. Benefiting from the electrostatic repulsion between ─SO − functional groups SO 4 2− anions strongly interaction 2+ cations, migration can be restricted, 2D diffusion ions at surface electrode suppressed, desolvation hydrated promoted. Concurrently, homogeneous nanochannels within ensure uniform electric field ion flux. With these benefits, enables Zn//Zn cells run stably 1200 h mAh cm −2 by facilitating oriented dendrite‐free deposition. Under a depth discharge 68.3%, life span 400 still achieved. Additionally, reliability confirmed in Zn//MnO 2 Zn//H 11 Al V 6 O 23.2 full high mass loading conditions. This work provides valuable guidance advancement high‐performance separators AZIBs.

Abstract The practical realization of aqueous zinc‐ion batteries relies crucially on effective interphases governing Zn electrodeposition chemistry. In this study, an innovative solution by introducing ultrathin (≈2 µm) biomass membrane as intimate artificial interface, functioning nature's ion‐regulation skin to protect zinc metal anodes is proposed. Capitalizing the inherent properties natural reed membrane, including multiscale ion transport tunnels, abundant ─OH groups, and remarkable mechanical integrity, demonstrates efficacy in regulating uniform rapid 2+ transport, promoting desolvation, (002) plane electrodeposition. Importantly, a unique situ electrochemical Zn─O bond formation mechanism between electrode upon cycling elucidated, resulting robustly adhered interface covering anode surface, ultimately ensuring dendrite‐free highly reversible anodes. Consequently, approach achieves prolonged cycle life for over 1450 h at 3 mA cm −2 /1.5 mAh symmetric Zn//Zn cells. Moreover, exceptional cyclic performance (88.95%, 4000 cycles) obtained active carbon‐based cells with mass loading 5.8 mg . offers cost‐effective environmentally friendly strategy achieving stable batteries.
