Synthesis and characterization of Li2MnSiO4/C nanocomposite cathode material for lithium ion batteries
- 化学化工－已发表论文 
A high capacity LiMnSiO4/C nanocomposite cathode material with good rate performance for lithium ion batteries through a solution route has been successfully prepared. The material is able to deliver a reversible capacity of 209 mAh g(-1) in the first cycle, i.e. more than one electron exchange can be reversible cycled in the materials. The highly dispersion of nanocrystalline Li2MnSiO4 which was surround by a thin film of carbon was attributed to the cause of excellent performance of the materials. Ex situ XRD and IR results show that poor cycling behavior of Li2MnSiO4 might be due to an amorphization process of the materials. (C) 2007 Published by Elsevier B.V.
