Abstract
The electrochemical performances of these graphite-maghemite composites were tested. The nanometric size of the maghemite grains, and consequently their great reactivity, allows a partial reversibility of the reaction between iron and maghemite. The corresponding capacity reaches 440 mAÂ h/g and makes such composites good candidates for anodes in lithium-ion batteries. However, the reversible capacity decreases during the electrochemical cycling due to the coalescence of the maghemite nanoparticles.
