Titanium nitride (TiN) has garnered much attention as a promising anode material for lithium ion batteries (LIBs) due to its abundance， non-toxicity， low cost and stable chemical properties. However， the poor ionic and electronic conductivities of TiN anode materials pose great challenges in satisfying the requirements of high energy-density batteries. In this paper， Co-doped TiN nanoparticles loaded on nitrogen-doped carbon was designed and prepared by sol-gel methods. The graphitization degree of carbon can be regulated by adding the difference amount of dicyandiamide (DCDA). Compared with the other prepared anode material， Ti_0.95Co_0.05N/NC exhibit higher specific capacity， and a high capacity retention of 530mAh·g^-1 after 120 cycles at 100mA·g^-1 current density.
