This study presents newly designed and produced solid Li-ion conductive composite layers based on polymer electrolytes and Li-ion-conducting particles. The composite layers are studied using AC impedance spectroscopy. The conductivity of the composite layers is 0.14 mS/cm at room temperature. We discuss the Li-ion transfer mechanism via a characteristic frequency of impedance analysis and show that the interior of Li-ion-conducting particles is the major Li-ion path. The activation energy is less than that of polymer electrolytes while being greater than that of the grain boundary of Li-ion-conducting particles. The newly designed composite layers could be utilized in solid-state Li-ion batteries and solid-state Li-air batteries.
