Graphitized mesoporous carbon/tin composite negative electrode material of lithium ion battery

The invention discloses a graphitized mesoporous carbon/tin composite negative electrode material of a lithium ion battery. The graphitized mesoporous carbon/tin composite negative electrode material with the nanotin embedded in the pore wall of graphitized mesoporous carbon is prepared by adopting mesoporous silicon oxide as a template, vegetable oil as a carbon precursor and hydrated tin chloride as a tin source through the steps of a simple solid liquid-grinding template method, high temperature heat treatment and silicon oxide removal. The composite material has stable performances, and has the advantages of high lithium storage capacity, long life and good safety as a negative electrode material in the lithium ion battery.
