    Abstract

    LiMO2 (M = Co, Ni) was prepared by complexing sol-gel processes. The phase and thermal stability were characterized by XRD and TG analyses. LiCoO2 and LiNiO2 phases are formed around 400 degrees C and 700 degrees C respectively in our synthesis process. LiNiO2 exhibit higher electrical conductivity and better H-2/O-2 fuel cell performance than LiCoO2 when used as cathode materials. But its thermal stability is relatively poorer than the later at intermediate temperature. (C) 1999 Elsevier Science BN. All rights reserved.
