Organic-modified LTO nanocrystals were first synthesized in supercritical methanol at a short reaction time of 15 min using oleylamine as a surface-modifier and as a carbon precursor. Subsequent calcination under inert conditions resulted in a highly crystalline LTO core with a size of 5-15 nm and highly graphitic carbon shell with a thickness of 0.7-2.3 nm. The obtained core-shell LTO/C nanocomposite exhibited superior high rate performance, long-term cyclability, and low-temperature discharge capacity.
