AbstractA new solid polymer electrolyte composed of a polyimide matrix, an ionic liquid additive (1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, [Bmim][TFSI]), and a lithium salt (lithium bis(trifluoromethanesulfonyl)imide, LiTFSI) is fabricated by the solution-casting technique. The obtained self-standing polyimide (PI)-based polymer electrolyte (PI-100% BmimTFSI-60% LiTFSI) membranes show a great flexibility, transparency, and infiltration ability. As a result of the high thermal stability of the polyimide matrix, the thermal decomposition temperature of the electrolyte is high (420 degrees C). The ionic conductivity can be up to 1.73 x 10(-5) S cm(-1) at room temperature and reaches 1.26 x 10(-3) S cm(-1) at 80 degrees C. In addition, the PI-100% BmimTFSI-60% LiTFSI electrolytes have a wide electrochemical stability window of 4.8 V, a general lithium ion transference number of 0.12, and good interfacial stability and compatibility. In particular, the assembled LiFePO4/Li half cells made from this polyimide-based electrolyte can light up a light-emitting diode lamp at room temperature.
