摘要
与传统合金相比,高熵合金因其独特的机械性能、优异的摩擦磨损抗力、出色的耐腐蚀性以及显著的结构稳定性而备受关注,在电磁和催化领域也展现出巨大潜力。聚焦高熵氧化物(high entropy oxide,HEOs)在水系锌离子电池中的创新应用,系统综述了其最新研究进展。阐述了HEOs在提升水系锌离子电池能量密度和循环稳定性方面的关键作用;详细分析了四种典型制备方法(机械合金化、电弧熔炼、溶液燃烧及共沉淀法)的技术特点;重点阐释了高熵氧化物的四大特征效应(高熵效应、晶格畸变效应、迟滞扩散效应和鸡尾酒效应)及其协同作用机制;深入探讨了元素掺杂调控策略对电化学性能的影响,并展望了HEOs在水系锌离子电池储能领域的发展方向。
Compared with traditional alloys,high-entropy alloys have attracted significant attention due to their unique mechanical properties,excellent wear resistance,remarkable corrosion resistance,and outstanding structural stability,while also demonstrating great potential in electromagnetic and catalytic applications.This review systematically summarizes recent advances in the innovative application of high-entropy oxides(High entropy oxide,HEOs)in aqueous zinc-ion batteries.The pivotal role of HEOs in enhancing energy density and cycling stability of zinc-ion batteries is first elucidated.Four typical synthesis methods(mechanical alloying,arc melting,solution combustion,and coprecipitation)are then analyzed in detail regarding their technical characteristics.Special emphasis is placed on elucidating the four characteristic effects(high-entropy effect,lattice distortion effect,sluggish diffusion effect,and cocktail effect)and their synergistic mechanisms in HEOs.Furthermore,the influence of elemental doping strategies on electrochemical performance is thoroughly discussed,along with perspectives on future development directions of HEOs for zinc-ion battery energy storage.
