Rational Design of Bimetal Nanoparticles Anchored Hierarchical Carbon Nanospheres with Abundant Active Sites for High-Performance Liquid/Flexible Zinc-Air Batteries

Опубликована: Янв. 1, 2025

The development of highly active bifunctional electrocatalysts is crucial to the sluggish oxygen reduction reaction/oxygen evolution reaction (ORR/OER) for efficient wearable Zn–air batteries (ZAB). Fe-Nx-C moieties anchored on carbon supports emerge as a desirable alternative ORR catalysts but its OER activity suffers from low catalytic performance and stability. Herein, N-doped carbon-encapsulated Fe3C MnO nanoparticles composite (FeMn-NC) was developed using simple one-step pyrolysis self-sacrificial template. obtained FeMn-NC possess hierarchical porous structure with large specific surface area rich pyridinic N, which are favorable exposure sites. introduction Fe3C/MnO interface can regulate charge redistribution promote ORR/OER kinetics, confirmed by theoretical calculations. exhibits an excellent in alkaline electrolytes.The assembled liquid ZAB cathode achieve ultrahigh capacity 831.7 mAh g-1 charge-discharged stability up 800 h at 10 mA cm⁻² (2400 cycles). Furthermore, corresponding flexible solid-state provides stable open-circuit voltage 1.50 V 676.1 g−1 1.0 cm-2 good cycling This work offers strategy synthesize materials properties, be applied other electrochemical energy devices.

Representative By‐Products of Aqueous Zinc‐Vanadium Batteries: Origins, Roles, Strategies, and Prospects

Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 3, 2025

Abstract Aqueous zinc‐ion batteries (AZIBs) are of interest in next‐generation energy storage applications owing to their safety, environmental friendliness, and cost‐effectiveness. Vanadium‐based oxides promising cathodes for AZIBs due appropriate structure multielectron redox processes. Although hundreds studies devoted understanding the mechanisms developing high‐performance vanadium‐based cathodes, many puzzles controversies still exist, especially regarding two representative by‐products, basic zinc salt (BZS) pyrovanadate (ZVO). BZS ZVO often observed on cathode anode during cycling, directly affecting battery performance. However, by‐products’ controversial unclassified insights unclear have severely limited Zn‐V batteries’ progress. Therefore, this review aims exhaustively elucidate “past present” by‐products following a logical sequence origin, role, inhibition strategy, prospect. Notably, incorporates substantial comments understandings long‐neglected issues related BZS‐related ZVO‐related dissolution mechanisms. This is expected provide scientific guidelines future optimization commercialization batteries.
