• The electrochemical properties of LiNi_<1-y>Al_yO_2 (0<___y<___0.1) powder prepared by emulsion method were investigated. The emulsion-derived powder was calcined at the temperature range of 700-800℃ for various times. A single phase of LiNi_<1-y>Al_yO_2 solid solution was formed at 750℃. The composition of LiNi_<0.99>Al_<0.01>O_2 synthesized at 750℃ for 36 h demonstrated the largest discharge capacity and showed an improved cycle life. The initial and final discharge capacities were 168 and 156 mAh/g, respectively, during 20 cyclic tests. The fading rate in discharge capacity after 20 cycles was only 7%, which was lower than the 8.7% of LiNiO_2. The optimum condition for the synthesis of LiNi_<1-y>Al_yO_2 was by heating at 750℃ for 36 h in an oxygen stream.
