At the moment Li-ion batteries are dominating in the segment of energy storage for portable electronics and electric drivetrains. Despite its overall popularity and widespread, the Li-ion technology has a high improvement potential, especially in the aspects concerning power and energy density, power fading, safety etc. Besides the variety of different factors, the chemical, mechanical and morphological uniformity of the cell components is one of the aspects crucial for optimization, estimation and prediction of cell parameters and cell behavior during standard operation and misuse. In the current contribution a series of diffraction-based methods (spatially resolved diffraction using radial oscillating collimators and\or conical slits as well as X-ray and neutron diffraction tomography) applied to probe inner structure of of samples (eithe on example of dedicated phantom sample or cylinder-type Li-ion battery) will be briefly introduced and reviewed.
