ABSTRACT

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.
