Oleic-acid-assisted carbon coating on Sn nanoparticles for Li ion battery electrodes with long-term cycling stability

We report the one-pot synthesis of high-performance Sn@C nanocomposite anode materials obtained by uniform carbon coating onto Sn nanoparticles induced by electrical Sn-wire explosion in oleic acid liquid media at roomtemperature. This Sn@C nanocomposite exhibits highly reversible Li-storage performance with a specific capacity of similar to 730 mA h g(-1), even after 200 cycles.
