Synthesis of macroporous carbon materials as anode material for high-performance lithium-ion batteries

摘要

In this paper, a type of macroporous carbon (MPC) material was produced using water-soluble sodium carbonate (Na2CO3) as the template and glucose as the carbon precursor. After annealing in an argon atmosphere (Ar) at 700 degrees C, the samples exhibited specific surface areas up to 600m(2)g(-1) with different proportions of sodium carbonate and glucose. When the samples were employed as anode materials in lithium-ion batteries, the electrodes delivered a stable reversible capacity at 200 mAg(-1) and favourable cycling stability at 500mAg(-1). Moreover, all MPC samples exhibited excellent rate performances at 5000mAg(-1).
