文摘

Effective ionic conductivity is evaluated by experiment, simulation and modeling. Effects of binder volume and morphology in cathode are considered. Effects of particle morphology and orientation in anode are considered. Correlation equation of porous structure and ionic conductivity is obtained. Difference between actual conductivity and physical limiting is understood.
