SiOx　is　regarded　as　a　promising　anode　material　for　the　next-generation　lithium-ion　batteries　with　high　energy　density.　However,　the　reduplicative　volume　changes　during　cycling　cause　the　pulverizations　of　Si,　leading　to　decreased　utilization　of　active　Si　component　and　poor　cycling　performance.　Herein,　a　facile　and　scalable　Fe-Cr　decorating　strategy　is　reported　to　boost　the　lithium　storage　of　SiOx　anode.　Our　comprehensive　characterizations　indicate　that　there　are　strong　interactions　between　Fe-Cr　and　SiOx　during　a　facile　ball　milling　process.　After　cycling,　Fe-Cr　nanoparticles　are　dispersed　in　the　in-situ　formed　lithium　silicates　and　Li2O　matrix,　which　can　maintain　superior　conductivity　of　lithium　ion　and　electron　for　the　active　components　through　point-to-point　connections.　This　unique　structure　boosts　the　electrochemical　de-alloying　process　of　the　low-valent　LixSi　(0　≤　x　≤　2),　and　increases　effective　utilization　of　the　active　Si　component　during　cycling,　resulting　in　improvement　of　reversible　capacity　and　cycling　stability.　This　bm　SiOx-FeCr　electrode　can　deliver　high　reversible　specific　capacity　(1370　m　Ah　g−1　at　200　mA　g−1),　good　rate　capability　(653.8　m　Ah　g−1　at　2000　mA　g−1),　and　superior　cycling　stability.　This　work　provides　a　promising　route　for　improving　the　utilization　of　active　Si　component　and　the　structural　stability　of　SiOx-based　anodes.　©　2021
