Lithium borate/silica composites, 40 wt% SiO 2 with x•Li 2 O + (1-x)•B 2 O 3 , x = 0.33, 0.50, were explored with the goal of achieving Li-ion conductivity enhancements across batches with different compositions and processing steps. Two batches were made for each composition, namely micron and nanoscale batches, which differ in their processing and fabrication methods. Phase and microstructural characterization showed a composite which is consisted of a conductor-rich and an insulator-rich region. Previous dispersed ionic conductors, in which conductivity is enhanced by the insulator/conductor interaction, were modeled mostly by percolation models. However, these percolation models are not compatible with conventional impedance spectroscopy circuit models and complex non-linear regression analysis. Hence, new circuit models were created based upon a
