Zincophilic Design for Highly Stable and Dendrite‐Free Zinc Metal Anodes in Aqueous Zinc‐Ion Batteries

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

Published: Sept. 13, 2024

Abstract Aqueous zinc‐ion batteries represent a highly promising next‐generation electrochemical energy storage system because of their safety, environmental friendliness, resource abundance, and simple assembly conditions. However, the formation growth zinc dendrites on anode seriously hinder practical application batteries. Zincophilic design, which enables uniform nucleation/deposition, offers an effective solution to achieve dendrite‐free anodes. Despite significant progress in field zincophilic research this currently lacks clear analysis guidance. This paper provides comprehensive overview current status design mechanism for from three aspects: construction layers, addition additives electrolyte, 3D host. Moreover, challenges facing industrialization commercialization further are briefly discussed.

Coupling Bifunctional Scaffolds with Slow Photon Effect for Synergistically Enhanced Photoassisted Lithium–Sulfur Battery Properties

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 25, 2025

Photoassisted lithium-sulfur (Li-S) batteries offer a promising approach to enhance the catalytic transformation kinetics of polysulfide. However, development is greatly hindered by inadequate photo absorption and severe photoexcited carriers recombination. Herein, photonic crystal sulfide heterojunction structure designed as bifunctional electrode scaffold for photoassisted Li-S batteries. Inverse opal (IO) structures utilize slow photon effect that originates from their adjustable band gaps, giving them distinctive optical response characteristics. The incorporation SnS/ZnS within these IO frameworks further broadens light spectrum enhances charge transfer process. This efficient hybrid not only adsorption conversion polysulfides at cathode but also induces uniform Li nucleation anode. These contribute full output high reversible capability 1072 mAh g-1 maintain stable cycling 50 cycles. Additionally, specific capacity 698.8 still obtained even under sulfur loading up 4 mg cm-2. present strategy on battery properties can be extended rationally construct other energy storage devices.

ACS Nano, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 18, 2024

Aqueous Zn-ion batteries have garnered significant attention as promising and safe energy storage systems. Due to the inevitable dendrite corrosion in metallic Zn anodes, alternative anodes of intercalation-type materials are desirable, but they still suffer from low efficiency, unsatisfactory capacity, insufficient cycle life.
