| 英文摘要 | reconstruction and characterization of the porous composite electrode via experimental and numerical approaches are the basis and prerequisite of pore-scale modeling. the monte carlo approach was employed to reconstruct the licoo2 cathode of a li-ion battery. the reconstructed electrode resolves sub-micrometer microstructure, thus evidently distinguishing the three individual phases: licoo2 as active material, pores (electrolyte), and additives. an extensive characterization was subsequently performed to calculate some important structural parameters and transport properties, including the geometrical connectivity and the specific surface area, etc. particularly, a self-developed d3q15 lb (lattice boltzmann) model was used to calculate the effective thermal (or electric) conductivity and the effective species diffusivity in electrolyte (or solid) phase, and the tortuosity of an individual phase. the reconstructed 3d microstructure is consistent with the real cathode microstructure concerning several important statistical features including porosity, volume fraction of each phase, and two-point correlation functions etc. lb model predictions indicate that the effective transport coefficients are closely related to the micro-morphology in electrodes. |
