Characterization of La0.6Sr0.4CoO3-α cathode powder prepared by a combined citrate-EDTA method / Abdullah Abdul Samat, Mohd Azlan Mohd Ishak and Nafisah Osman

The La0.6Sr0.4CoO3-α (LSCO) cathode powder was prepared by a combined citrate-EDTA method using nitrate based chemicals. Citric (CA) and ethylenediaminetetraacetic acid (EDTA) were used as chelating agents and ethylene glycol (EG) as a polymerizing agent. The formation of metal complexes of LSCO was...
