The AC electrical response of pressed powder pellets formed with electrically anisotropic bidimensional and monodimensional solid electrolyte particles has been calculated using the Percolation Effective Medium Theory (PEMT) approximation. The pellet is represented by a mixture of a conducting phase (solid electrolyte)and an isolating one (air). The derived results show the importance of the microstructure parameters and their interrelations in the pellet response and reveal which inmitance functions contain the most information about the particle real electrical properties, This microstructure influence on the pellet response can be used to improve the ’bulk’ ionic conductivity in the pellets. The use of this model is useful in the understanding of the pellet response in order to obtain the anisotropic electrolyte real electrical characteristics.
