(C/LFP) nanoparticles have been prepared successfully by a spray-drying process combined with a calcination step using cellulose as carbon source. LiOH plays duple roles as agency for dissolving cellulose with aqueous solution and source of lithium for LiFePO

. The synthesized C/LFP composite microspheres are rich in porosity, and all the C/LFP microspheres consist of numerous LiFePO
4
grains with a diameter of about 200 nm. In addition, the individual LiFePO
4
grains are encapsulated by the carbon matrix derived from cellulose. The carbon cladding enhances the electronic conductivity of LiFePO
4
, while the porous structure shortens the Li
+
diffusion distance and facilitates the penetration of electrolyte when the C/LFP composites are used as cathode material for the battery. Hence, the unique composites delivered an initial specific discharge capacity of 165 mAh g

and showed good rate performance.
