To　accelerate　the　commercial　implementation　of　high-energy　batteries,　recent　research　thrusts　have　turned　to　the　practicality　of　Si-based　electrodes.　Although　numerous　nanostructured　Si-based　materials　with　exceptional　performance　have　been　reported　in　the　past　20　years,　the　practical　development　of　high-energy　Si-based　batteries　has　been　beset　by　the　bias　between　industrial　application　with　gravimetrical　energy　shortages　and　scientific　research　with　volumetric　limits.　In　this　context,　the　microscale　design　of　Si-based　anodes　with　densified　microstructure　has　been　deemed　as　an　impactful　solution　to　tackle　these　critical　issues.　However,　their　large-scale　application　is　plagued　by　inadequate　cycling　stability.　In　this　review,　we　present　the　challenges　in　Si-based　materials　design　and　draw　a　realistic　picture　regarding　practical　electrode　engineering.　Critical　appraisals　of　recent　advances　in　microscale　design　of　stable　Si-based　materials　are　presented,　including　interfacial　tailoring　of　Si　microscale　electrode,　surface　modification　of　SiOx　microscale　electrode,　and　structural　engineering　of　hierarchical　microscale　electrode.　Thereafter,　other　practical　metrics　beyond　active　material　are　also　explored,　such　as　robust　binder　design,　electrolyte　exploration,　prelithiation　technology,　and　thick-electrode　engineering.　Finally,　we　provide　a　roadmap　starting　with　material　design　and　ending　with　the　remaining　challenges　and　integrated　improvement　strategies　toward　Si-based　full　cells.
