摘要
The present invention relates to a process for preparing porous tin-carbon-silica composites. Using a self - assembly of the block copolymer and the precursor, a complex with a tin substance confined inside the carbon - silica support as a one - pot is synthesized. The synthesized tin - carbon - silica composites have high capacity and stability when applied to lithium ion battery cathode materials. The present invention relates to a precursor mixture comprising a metal precursor, a carbon precursor, and a silica precursor; A block copolymer comprising a block to which the metal precursor is bonded and a block to which a carbon precursor and a silica precursor are bonded; And a solvent, and self-assembling and firing the mixture, wherein the metal is dispersed in the carbon-silica support.
