Synthesis and properties of CoO2, the x = 0 end member of the LixCoO2 and NaxCoO2 systems

T. Motohashi, Y. Katsumata, T. Ono +3

We report here the synthesis of single-phase bulk samples of CoO2, the x = 0 end member of the AxCoO2 systems (A = Li, Na), from a pristine LiCoO2 sample using an electrochemical t…
