SiOC　as　an　alternative　silicon-based　material　possesses　great　potential　in　lithium　ion　batteries　due　to　its　high　reversible　capacity,　tunable　chemical　component　and　various　synthetic　route.　However,　large-scale　production　of　SiOC　powders　grinded　from　SiOC　bulks　is　restricted　in　commercial　application　because　of　the　poor　electrical　conductivity.　Herein,　three　dimensional　(3D)　lamellar　SiOC@C/rGO　composite　is　fabricated　through　hydrothermal　reaction　and　electrostatic　self-assembly　process,　in　which　SiOC　powders　encapsulated　by　amorphous　carbon　layers　are　homogeneously　dispersed　in　graphene　sheets.　Cfree　nanoclusters　in　SiOC,　carbon　layers　on　SiOC　surface　and　graphene　supporters　in　the　composite　establish　the　multidimensional　interconnected　conductive　architecture　and　possess　favorable　interfacial　adhesion.　Therefore,　SiOC@C/rGO　exhibits　high　specific　capacity　(676　mAh　g−1　at　200　mA　g−1)　and　remarkable　rate　capability　(306.4　mAh　g−1　at　4000　mA　g−1).　The　full　cell　assembled　with　this　anode　and　LiFePO4　cathode　also　demonstrates　stable　voltage　platform　and　good　performance　for　200　cycles.　The　excellent　performance　of　SiOC@C/rGO　profits　from　the　synergistic　effect　of　robust　construction,　multidimensional　conductive　architecture　and　chemical.　Composition:　The　proposed　strategy　can　also　be　developed　to　prepare　other　materials　with　graphene　layer　to　enhance　their　electrical　conductivity　for　commercial　application.　©　2021　Elsevier　Ltd
