In the reported work, we reconstruct a LiCoO2 cathode three-dimensionally, for the first time differentiating between all three constituents: (i) active material, (ii) binder and (iii) pore space for this specific material. We apply a hybrid method of manual and gray-scale threshold segmentation to reconstruct a cuboid with a volume of approximately 4500 mu m(3). The reconstructed geometry is characterised to support the data basis of homogenized cathode models. We solve numerically for electrical conductivity and derive electrical tortuosity analytically from the result. Pore space connectivity and pore size distribution are calculated.
