Abstract

Li-based materials, previously used in lithium batteries, are now actively applied in solid-oxide fuel cells (SOFCs). The synthesis and characterisation of LiCo0.6Zn0.4O2 (LCZO) cathode powder calcined at 600 °C for SOFC application has been reported. In the present work, LCZO powder was calcined at 700 °C and its properties were investigated. Results showed that the impure phases recorded through X-ray diffraction (XRD) in a previous work decreased with the ZnO phase at approximately 37.4%, and 62.6% of LCZO remained. Transmission electron microscopy was used to study the morphology of the calcined powder, wherein the crystallite size obtained from XRD well agreed with the XRD analysis result. The LCZO particle size calcined at 700 °C was examined with a particle-size analyser. The electrical conductivity of bulk pellet was tested at 400-700 °C, and the highest conductivity of 9.90 Scm-1 was recorded at 700 °C. Overall, this material exhibited excellent potential for proton-conducting SOFCs application.
