Compression curves of LiCoO₂. The line is a Birch–Murnaghan equation fitted to the present experimental data. The dotted line is a Birch–Murnaghan equation fitted to the theoretical calculation data. The solid diamonds are the static compression data from Ref. [8]. The solid circles are the static compression data obtained by Xu et al.^[5]
