An ordered mesoporous carbon (OMC) with controllable molecule crystal and platelet graphitic pore walls, which is directionally grown on the internal pore walls of SBA-15 or anchors at liquid/silica interfaces by molecule engineering, has been investigated as lithium ion anodes. It is found that the OMC exhibits high kinetics, rate and cycling performance. The i0 and DLi are almost constant after 50 cycles. OMC shows a high reversible specific capacity of 153.9 mAh g-1 at the current density as high as 3500 mA g-1. The excellent electrochemical performance could be attributed to the presence of the porosity and platelet graphitic pore walls.
