Abstract

We demonstrate the fabrication of hybrid nanocomposite electrodes with a combination of SnO 2 nanoparticles (NPs) and conducting multiwalled carbon nanotube (MWCNT) anodes (SnO 2@CNT) through the direct anchoring of SnO 2 NPs on the surface of electrophoretically pre-deposited MWCNT (EPD-CNT) networks via a metalorganic chemical vapor deposition process. This SnO 2@CNT nanocomposite displays large reversible capacities of over 780, 510, and 470 mAh g -1 at 1 C after 100, 500, and 1000 cycles, respectively. This outstanding long-term cycling stability is a result of the uniform distribution of SnO 2 NPs (∼8.5nm), a nanoscale EPD-CNT network with good electrical conductivity, and the creation of open spaces that buffer a large volume change during the Li-alloying/dealloying reaction of SnO 2.
