Comprehensive analyses on the complex ion transport of co-planar interdigitated microelectrode arrays in solid-state ionic devices were carried out using finite element and analytical methods. We found that the ion flux between anode and cathode was constricted on the edges of both electrodes. Based on these results, we defined/analyzed the effective length and ohmic area-specific-resistance of various cell configurations (i.e., electrode width and electrolyte thickness). Using the relation between the effective length and the ohmic area-specific-resistance, we found an analytical model having favorable agreement with the finite element results and propose design rules for high-performance and densely integrated devices.
