Obtención de nanopartículas de LiCoO2 mediante síntesis por combustión de soluciones

ABSTRACT Lithium Cobalt Oxide (LiCoO2) nanoparticles were obtained by the Solutions Combustion Synthesis method, using starch as fuel. Four starch/nitrates ratios (φe) (ranging 0.5-1.25) have been studied. One route was a conventional, stoichiometric process, while the other ones were a nonstoichiometric process. The samples were calcined in air at 773K. The synthesized material was analyzed by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, electrochemical charge-discharge and rate capability curves. It was identified that in all cases, powders exhibited rh...
