| Резюме: | Electrode microstructures of a high energy and a high power lithium-ion cell were analyzed in 3D using tomographic methods. Calculation of structural parameters enabled a quantitative comparison of the electrodes. To simulate their electrochemical behavior a finite element model was developed which, for the first time, includes a real particle size distribution. This allowed for an identification of the limiting mechanisms during charging and discharging in the electrodes of both cells. |
