Phase pure LiNiO2 was prepared using a solid-state method and the optimal synthesis conditions led to a remarkably high capacity of 200 mA h g(-1) with excellent retention. The combination of bulk and surface characterization elucidated an essential role of the excess Li in phase formation during synthesis and the subsequent electrochemical performance.
