The advancement of aqueous zinc-based batteries is greatly restricted by zinc dendrites. One potential solution to this challenge lies in the employment high-modulus separators. However, achieving both high modulus and large ionic conductivity a single separator remains formidable task. Inspired wood architecture, study breaks trade-off designing an anisotropic biodegradable separator. This design significantly improves along oriented direction while simultaneously facilitating fast Zn2+ ion transport through aligned vertical channels. Additionally, configuration resolves contradiction between low thickness good dendrite-inhibition capability. These benefits are supported finite element simulations comprehensive experimental validation, which also underscore critical role enhancement for By employing separator, prolonged life span realized Zn||Zn cells, with improved cyclability full batteries. work presents strategy modification towards dendrite-free metal plays crucial mitigating dendrites side reactions zinc-ion Here, authors break ability.

A Comprehensive Strategy Enables High‐Loading BiOBr@BiOIO₃ Cathodes for Quasi Ah‐Level Aqueous Zn‐Ion Batteries

Small, Год журнала: 2025, Номер unknown

Опубликована: Фев. 27, 2025

Abstract Aqueous Zn‐ion batteries (AZIBs) recently have attracted broad attention. To achieve high energy density of AZIBs, constructing high‐loading cathodes is the prerequisite. However, cycling stability still faces great challenges. Herein, a comprehensive strategy proposed to improve structural cathode material and mechanical cathode. The BiOBr@BiOIO 3 heterostructure are successfully constructed via sharing interfacial oxygen atoms, in which effect can effectively enhance reaction dynamics stability. Meanwhile, biomimetic binder skillfully designed situ dual cross‐linking between guar gum cation ions application water‐based sustainable polymer AZIBs. Density functional theory calculations demonstrate possesses strong affinity toward firmly adhere active materials. Quantitative nanomechanic technology visually demonstrates robust properties as‐obtained As result, when loading increases as 100.71 mg cm −2 , an ultrahigh areal capacity 20.02 mAh be achieved. Specially, quasi‐Ah‐level (0.244 Ah) pouch‐type cell with 1.17 g constructed, showing practical potential.
