Thermostability and phase transformation of LiCu2O2, LiCu3O3 and other related copper oxides have been studied by x-ray powder diffraction technique at high temperature in air. Both LiCu2O2 and LiCu3O3 are metastable at room temperature. LiCu2O2 decomposes to Li2Cuo2 and a monoclinic phase with CuO structure while LiCu3O3 transforms to the monoclinic phase at lower temperature. Moreover evidence for a possible intermeiate phase between LiCu3O3 and Li0.25Cu0.75O0.85 has also been presented.
