Design and Structure of Electrolytes for All‐Weather Aqueous Zinc Batteries

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 1, 2024

Abstract Rechargeable aqueous zinc batteries (AZBs) utilizing water‐borne electrolytes are intrinsically safe electrochemical devices that promising in next‐generation energy storage. Such application requires adaptivity to global climate, especially at grid‐scale, thus their stability of performance varying temperatures is critical. Many essential properties AZBs, i.e., ion transfer, redox kinetics, etc., largely governed by the because relatively limited stable phase temperature water. This limitation extremely vital cold regions since charging and discharging become more difficult sub‐zero range due water freezing. Despite development various electrolyte strategies recent years, comprehensive reviews focusing on this topic remain limited. research diverse reasons underneath failure AZBs extreme provides a thorough analysis possible resolutions from an perspective. It starts with challenges faced both high low concerning electrolytes. Different addressing these discussed, providing insights into under conditions. Finally, review concludes summary outlook design structure for all‐weather integrating innovative non‐aqueous battery systems.

Abstract The economically unfeasible electrochemical breakdown of water is linked to the production materials with low overpotential using a simple method. study demonstrates fabrication and use samarium oxide (Sm 2 O 3 ) on carbon nanotubes (CNTs) as an effective long‐lasting electrocatalyst for oxygen evolution reaction (OER). X‐ray diffraction analysis confirms Sm embedded CNTs /CNTs) phases 0.052 nm lattice strain, while scanning electron microscopy structural shows ball‐like shape 78 average particle size. synthesized catalyst performs well, attaining current density 10 mA cm −2 having onset potential 1.33 V versus reversible hydrogen electrode (RHE). In contrast CNT, which exhibit higher overpotentials 311 342 mV corresponding Tafel slopes 62 83 dec −1 , respectively, ‒CNT has slope 38 lower 276 mV. With more than 50 demonstrated remarkable stability over 180 h. impedance spectroscopy attributed robust ionic conductivity K⁺ ions, their small hydration sphere, reduced R ct value 3.4 Ω. composite long‐term OER electrocatalysis substitute been through promising results.
