As anode materials for Lithium-ion batteries, mesoporous materials such as mesoporous carbon can deliver high rate and stability on cycling owing to their unique mesostructure. Especially, the critical dimensions of pore size and wall thickness may highly influence the rate of intercalation. Herein a novel mesoporous carbon with increased pore size and decreased pore wall thickness is prepared by sacrificing Sn nanoparticles embedded in the carbon wall of CMK-3, and exhibits superior cycle and rate performances than normal CMK-3. Thus the structural parameters of mesoporous carbon are very important to its electrochemical performance and should be optimally controllable. (C) 2015 Elsevier Ltd. All rights reserved.
