Conversion reactions of interstitial-free 3d metal oxides
are candidate anodes for lithium ion batteries aimed at
achieving higher specific capacities than graphite.
This project targets on the synthesis of
nanoscale metal oxide particles
and the investigations of their electrochemical performance
as a reversible lithium storage compound. The following
chart showed the formation mechanism of disk-like iron oxide
microparticles and its CVD post-treatment products. Results
showed that the C/
γ-Fe2O3
nanostructures with large surface area and nanoscale carbon
coating layer exhibit a mixed-conducting property, and thus
deliver an improved cycling performance.
