In the study, the effect of TiSiO4 filler on the ionic conductivity of polymer composite electrolyte (PCE) was investigated. The PCEs use PEO/PVdF blend as polymer matrix, doped with lithium perchlorate (LiClO4), polypropylene carbonate (PC) as plasticizer, and titanium silicon oxide (TiSiO4) as a filler. The ionic conductivity of the CPEs was measured by AC impedance, and the crystallinity of the CPEs was investigated by using DSC and XRD, and the SEM image showed the morphology change of composite electrolyte. By the addition of TiSiO4 filler, the crystallinity was decreased and ionic conductivity was increased. It was found that the ion conductivity of polymer composite electrolytes depended on the content of doped filler and the filler could effectively reduce the crystallinity of the polymer matrix. |
