5) The cathode material, CoO2, is an example of a layered metal oxide. The structure of the oxide is critical, as it allows for the reversible association and dissociation of Li cations. The unit cell of LiCoO₂ is shown below along with the metric parameters for a series of non-stoichiometric oxides (LixCoO₂). Describe how the metal oxide changes in response to varying amounts of Li.
