Abstract :
In this paper, we report a simple method to synthesize LiFePO4/carbon-network composite using the reproducible, natural sawdust as carbon precursor and Fe2O3 as Fe-source.The phase purity of the composite was examined by X-ray diffraction, and powder morphology was observed by TEM. The composites were composed of spherical particle and amorphous network structure.
