PVA-assisted sol-gel method is useful in producing metal oxides with large surface area at low temperature. We fabricated LiCoO{sub 2}-coated NiO(LC-NiO) cathode by PVA-assisted sol-gel method and measured its properties, The electrical conductivity of LC-NiO cathode was measured to be more than 5 times as high as that of NiO and unit cell test showed improved performance. From the SEM images and Raman spectra. we confirmed that the structure of LC-NiO was different from that of NiO. For 250 hours of steady operation of unit cells. the mean voltage of the cells were 0.78V for NiO and 0.85V for LiCoO{sub 2}-Coated NiO at a current density of l50mA/cm{sup 2}.
