Abstract
An embodiment of the present invention provides a method for preparing a silicon-carbon-graphene composite, comprising the steps of: (step 1) adding a carbon precursor solution to silicon and performing wet grinding so as to prepare a suspension: (step 2) forming a silicon-carbon composite by spray drying the suspension; and (step 3) spray drying and heat treating a solution comprising the silicon-carbon composite and graphene oxide.
