Future Long Cycling Life Cathodes for Aqueous Zinc‐Ion Batteries in Grid‐Scale Energy Storage

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 21, 2025

Abstract Developing sustainable energy storage systems is crucial for integrating renewable sources into the power grid. Aqueous zinc‐ion batteries (ZIBs) are becoming increasingly popular due to their safety, eco‐friendliness, and cost‐effectiveness. However, challenges remain in achieving realistic time per charge, long cycling life, high capacity practical conditions. Despite advancements cathode materials, issues such as dissolution side reactions limit performance. Optimizing architecture electrolyte composition essential address these challenges. Tailored formulations can stabilize electrode‐electrolyte interface (EEI enhance stability. This perspective reviews cathodes from past decades compares performance under different current densities. Emphasizing low density extended stability widespread adoption of ZIBs grid‐scale applications. By focusing on aspects, this aims bridge gap between research applications, offering insights optimizing material structure selecting matching electrolytes storage. work guides future developments ZIB technology, facilitating transition lab real‐world deployment.

Achieving Stable Alkaline Zinc–Iron Flow Batteries by Constructing a Dense Cu@Cu₆Sn₅ Nanoparticle Functional Layer

ACS Materials Letters, Journal Year: 2024, Volume and Issue: 6(9), P. 4028 - 4035

Published: July 31, 2024

Aqueous alkaline zinc–iron flow batteries (AZIFBs) offer significant potential for large-scale energy storage. However, the uncontrollable Zn dendrite growth and hydrogen evolution reaction (HER) still hinder stable operation of AZIFB. Herein, dense Cu@Cu6Sn5 core–shell nanoparticles are constructed on graphite felt (Cu@Cu6Sn5/GF) to induce zinc plating inhibit HER simultaneously. The charge transfer within Cu6Sn5 alloy shell provides a negative Cu, increasing its ability attract Zn. lack electrons in Sn makes it difficult undergo HER, which is confirmed by total internal reflection imaging method. Meanwhile, Cu core can increase conductivity between interface GF Cu@Cu6Sn5. As result, Cu@Cu6Sn5/GF electrode demonstrates superior cycling performance AZIFB with an average Coulombic efficiency 99.3% 700 cycles achieves maximum power density 487.6 mW cm–2. This strategy also be applied other Zn-based batteries.

Epitaxial Electrodeposition of Zinc on Different Single Crystal Copper Substrates for High Performance Aqueous Batteries

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

Published: Jan. 21, 2025

The aqueous zinc metal battery holds great potential for large-scale energy storage due to its safety, low cost, and high theoretical capacity. However, challenges such as corrosion dendritic growth necessitate controlled deposition. This study employs epitaxy achieve large-area, dense, ultraflat plating on textured copper foil. High-quality foils with Cu(100), Cu(110), Cu(111) facets were prepared systematically compared. results show that is the most favorable deposition, offering lowest nucleation overpotential, diffusion energy, interfacial a Coulombic efficiency (CE) of 99.93%. sets record flat-zinc areal loading at 20 mAh/cm2. These findings provide some clarity best-performing crystalline facets, Cu(111)/Zn(0002) ranking highest. Using MnO2-Zn full cell model, research achieved an exceptional cycle life over 800 cycles in cathode-anode-free configuration.
