摘要：
Disclosed is a tin-carbon mesoporous composite for a lithium ion battery negative electrode material, and a method for preparing the same. Using a mesoporous molecular sieve as a template, the precursors of tin and carbon are caused to fill the mesopores of the template and carbonized under nitrogen to obtain a composite of stannic oxide and carbon, and the stannic oxide is encapsulated by the carbon; and then the tin-carbon mesoporous composite for lithium ion battery negative electrode material is obtained by hydrothermal treatment, carbonization, etching, and high temperature carbothermic reduction. The tin-carbon mesoporous composite for lithium ion battery negative electrode material synthesized in the present invention has a reversible capacity of 550 mAh·g−1, after 100 cycles at a current density of 500 mA·g−1.
