摘要
The present invention relates to a method for preparing a porous tin-carbon-silica composite. A composite with a form in which tin material is contained in a carbon-silica supporter is synthesized with one-pot by self-assembling block copolymers and a precursor. The synthesized tin-carbon-silica composite has high volume and stability when being applied as a cathode material for a lithium-ion battery. Provided is a method for preparing a composite in which metal is dispersed on the carbon-silica supporter, comprising a step of self-assembling a precursor mixture including a metal precursor, a carbon precursor and a silica precursor; a block copolymer including a block with which the metal precursor is combined and a block with which the carbon precursor and the silica precursor are combined; and a mixture containing solvents.
