Silica-modified SnO2-graphene “slime” for self-enhanced li-ion battery anode

Silica is used to modify SnO2-loaded rGO, where Sn can diffuse into silica to plate on rGO, avoiding the aggregation of tin-lithium alloy. The silica-modified SnO2/graphene exhibits high capacity of mAh/g at 500 mA/g after 1000cycles.382
