Hard Carbon Prepared from Willow Leaves Using as Anode Materials for Li-Ion Batteries

Abstract:

Leaves, which are very easy to obtain freely, can be used as raw materials to prepare carbon materials. In this paper, we found that hard carbon can be prepared from willow leaves by one-step carbonization. When the hard carbon was used as anode materials for Li-ion batteries, the revisable capacity of the hard carbon was 230-260 mAhg^-1 at the current density of 37.2 mAg^-1 with a first-cycle coulombic efficiency of about 50 %. In addition, the hard carbon shows stable cycling performance and good rate capability.
