英文摘要	we adapt the simulated annealing approach for reconstruction of the 3d microstructure of a licoo2 cathode from a commercial li-ion battery. the real size distribution curve of licoo2 particles is applied to regulate the reconstruction process. by discretizing a 40 x 40 x 40 mu m cathode volume with 8,000,000 numerical cubes, the cathode involving three individual phases: 1) licoo2 as active material, 2) pores or electrolyte, and 3) additives (polyvinylidene fluoride + carbon black) is reconstructed. the microstructural statistical properties required in the reconstruction process are extracted from 2d focused ion beam/scanning electron microscopy images or obtained by analyzing the powder mixture used to make the cathode. characterization of the reconstructed cathode gives important structural and transport properties including the two-point correlation functions, volume-specific surface area between phases, tortuosity and geometrical connectivity of individual phase.
