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