摘要：Using comblike polymer PAALi-g-PEO as matrix, PAALi-g-PEO/LiClO4/LiTi2(PO4)(3) polymer electrolyte was prepare by casting. XRD, IR, SEM were used to study the effects of LiTi2(PO4)(3) Ultrafine Powder on the conductive properties of polymer electrolyte, and electrochemical impedance spectroscopy was used to test the ionic conductivity of polymer electrolyte. The results show that there is a " competitive complexation" between LiClO4 and LiTi2(PO4)(3) with PAALi-g-PEO, which can improve the surface morphology of polymer electrolyte; the conductivity of the polymer electrolyte reaches to a maximum of 4.6 x 10(-5)S.cm(-1), and is improved by 2 to 3 orders of magnitude compared with PEO/lithium salt system.
