Three-Dimensional C/SnO2 composites as anode materials for lithium ion batteries

The nano-carbon materials have attracted a lot of research interests since the discovery of C60 molecule in 1985 by Kroto et al. (1), and the first experimental evidence of tabular carbon structure from Iijima in 1991 (2). Current methods used for the preparation of nano-carbon materials, including chemical vapour deposition (CVD) and arc vaporisation (3), are commonly characterized by high cost and the high-pure carbonaceous precursor gasses. In this work, the potential of using coconut shell which is very cheap and readily available for the production of graphitic nano-carbon three-dimensional networks was investigated.
