Submicron particles of high voltage LiCoPO4 are prepared by sucrose-aided combustion synthesise as a preliminary arrangement for the construction of all-solid-sate lithium-ion battery. The obtained LiCoPO4 was assembled with Li2O-Al2O3-TiO2-P2O5 (LATP) solid electrolyte using spark plasma sintering (SPS) process in order to form enhanced electrical contacts. The reversible charge/discharge capacity of LiCoPO4 was obtained by cyclic voltammetry with a sweep rate of 0.5 mVs(-1) at 150 degrees C. It would be due to the enhanced interfacial contact between LiCoPO4 and LATP electrolyte without any voids, which was observed by the cross-sectional SEM images.
