title: In situ phase behaviour of a high capacity LiCoPO4electrode during constant or pulsed charge of a lithium cell.
abstract: The phase changes that occur during lithium extraction from LiCoPO4in lithium half-cells were studied using synchrotron X-ray diffraction. The existence of two two-phase regions with an intermediate phase present was observed. Significant variations in the composition of the phases of nominal stoichiometry LiCoPO4, Li2/3CoPO4and CoPO4resulted in unit cell volume variations. On current pulsing, lattice parameter shifts and phase recovery were directly observed.
