Lithium nickel oxide (LiNiO2) powders with an R3 m structure are successfully synthesized via a developed reverse microemulsion process. This method can effectively reduce the calcination temperature for synthesizing monophasic LiNiO2 powders to 700 ºC, which is much lower than that in the solid-state process. Nanosized LiNiO2 powders with narrow particle size distribution are obtained via the microemulsion process. Heating the precursors in pure oxygen results in the formation of LiNiO2 powders with an orderly arranged structure. The electrochemical analysis reveals that the microemulsion-derived LiNiO2 powders exhibit high discharge capacity and good cycleability.ABSTRACT
