摘　　要：Sodium-ion batteries(SIBs)have stepped into the spotlight as a promising alternative to lithium-ion batteries for large-scale energy storage systems.However,SIB electrode materials,in general,have inferior performance than their lithium counterparts because Nat is larger and heavier than Lit.Heterostructure engineering is a promising strategy to overcome this intrinsic limitation and achieve practical SIBs.We provide a brief review of recent progress in heterostructure engineering of electrode materials and research on how the phase interface influences Nat storage and transport properties.Efficient strategies for the design and fabrication of heterostructures(in situ methods)are discussed,with a focus on the heterostructure formation mechanism.The heterostructure's influence on Nat storage and transport properties arises primarily from local distortions of the structure and chemomechanical coupling at the phase interface,which may accelerate ion/electron diffusion,create additional active sites,and bolster structural stability.Finally,we offer our perspectives on the existing challenges,knowledge gaps,and opportunities for the advancement of heterostructure engineering as a means to develop practical,highperformance sodium-ion batteries.
