高熵氧化物特征性能及其在水系锌离子电池中的应用进展OA

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 appli-cation 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 co-precipitation)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,slug-gish 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.
