In the field of materials for Lithium ion batteries, the lithium iron phosphate LiFePO4 has been proven for use as a positive electrode due to its good resistance to thermal degradation and overcharge, safety and
low cost. The use of nanostructured materials would improve its
efficiency. This work shows the results of the synthesis of
nanostructured materials with functional properties for Lithium
batteries through aerosol techniques. The Spray Pyrolysis method allows
synthesizing nanostructured particles with spherical geometry, not
agglomerates, with narrow distribution of particle size and homogeneous
composition in respect to a precursor solution. Experimental techniques
were focused on the morphological (SEM and TEM), structural (XRD and
HRTEM-SAED), chemical (EDS) and electrochemical characterization.
