(a) A schematic drawing and a photograph of the gas-flow reactor for in situ diffraction, with an example contour plot of the PXRD patterns collected during the calcination of a reactant mixture of LiOH·H2O and Ni(OH)2, including hkl indices of the LiNiO2 product phase. Evolution of (b) lattice parameters (a and c), the zO coordinate of oxygen and the defect occupancy of NiLi during heating as well as (c) crystallite domain sizes during isothermal annealing experiments based on Rietveld refinements and results from a kinetic fitting analysis (Ostwald ripening model).
