Electrochemical Performance of the Composite Materials of Nano-Carbon and Graphite-Carbon

Abstract

Abstract: The composite materials of natural graphite (NG) and nano-scaled carbon were obtained by doping
with carbon nanotube (CNT) and carbon nanopowder (CNP) respectively. The Electrochemical performance of NG, CNT, CNP and their composite
materials were investigated as the anode materials of lithium ion batteries. The study shows carbon nanotube has large irreversible capacity loss and
its composite material is not suitable to anode for lithium ion batteries. There are good cooperation effect between CNP and NG, their composite
material shows very good electrochemical performance, compared with NG, its charge and discharge specific capacities increase by 9.8% and 9.4%,
respectively.

Key words: lithium ion battery, natural graphite, composite material, electrochemical performance
