Abstract	Polymer electrolytes composed of poly(ethylene oxide) (PEO), lithium oxalate (LiOX), and borontrifluoride diethyl ether (BF$_{3}$·OEt$_{2}$) were prepared, and their ionic conductivities, lithium ion transference number, thermal properties, and infrared spectra were investigated. The polymer electrolyte for the PEO/LiOX in the absence of BF$_{3}$·OEt$_{2}$ showed the ionic conductivity of 10$^{–6}$ S cm$^{−1}$ at 130 °C. The addition of BF$_{3}$·OEt$_{2}$ into the polymer electrolyte for the PEO/LiOX system induced an increase of the ionic conductivities by three orders of magnitude. IR spectra showed that in the polymer electrolyte for the PEO/LiOX system in the presence of BF$_{3}$·OEt$_{2}$, new interactions between LiOX and BF$_{3}$·OEt$_{2}$ and also between LiOX and PEO were observed. The polymer electrolyte for the PEO/LiOX system in the presence of BF$_{3}$·OEt$_{2}$ showed the lithium ion transference number of 0.55, which is higher than that (0.19) of PEO/LiTFSI polymer electrolyte. It was found that usage of the carboxyl discrete lithium salt for the polymer electrolyte is a promising method to improve lithium transference number. Figure ᅟ
