Insertion/De-insertion Processes and Rate Properties for LiFePO4
Searching for such Li1-δFePO4 and LiδFePO4 single-phase regions
Srinivasan,V taking into account both the diffusion of Li through the shell and the movement of the phase boundary, and raising the question of partial solid solution domains that are bound to exist.
Delacourt reported the existence of solid solutions at elevated temperatures.
Yamada suggested that solid solutions could exist at room temperature.
