Herein, a conductive polymer material containing rare earth oxide (PEG–LiX–CeO2) was designed and synthesized. The bonding performance of the conductive polymer was analyzed via AC impedance, X-ray diffraction (XRD), infrared spectroscopy (FTIR), scanning electron microscopy (SEM), tensile strength, ball milling and anodic bonding experiments. The AC impedance, XRD and FTIR experiments demonstrate that the introduction of alkali metal lithium salt and cerium oxide (CeO2) can effectively reduce the crystallinity of the composites and increase the ion migration. The results of ball milling show that increasing the milling time (< 10 h) and speed (< 250 r min−1) can improve the conductivity of the composites. The anodic bonding experiment of PEG–LiClO4–CeO2 with AL foil and the SEM characterization of the bonding interface demonstrate the existence of a well-defined bonding layer between the bonding interface.
