In this study, the one-step electrochemical preparation of chlorine doped and chlorine-oxygen containing functional group doped graphene-based powders was carried out by Yucel's method, with the resultant materials used as anode materials for lithium (Li)-ion batteries.
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.
Silicon and hematite, both important functional materials with high theoretical capacity, have been intensively investigated separately for application as anode materials in lithium ion batteries (LIBs).
Two-dimensional MXene nanomaterials are promising anode materials for Li-ion batteries (LIBs) due to their excellent conductivity, large surface area, and high Li capability.
