Gel type electrolyte was formulated by blending of PEDGA and PAN. PEDGA is a UV curable polymer which forms a chemical crosslink by UV or heat. Gel type electrolyte is very stable in ionic conductivity and interfacial resistance for a long storage time. It has the advantage of manufacturing the battery in a continuous process because oligomer crosslinking occurs in few seconds without heating. Discharge capacity and cycle life were increased by using LiPF 6 /LiCF 3 SO 3 mixed lithium salt and adding inorganic filler such as TiO 2 .

To develop a highly ion-conductive polymer electrolyte, we copolymerized methacrylonitrile (MAN) with ethylene glycol dimethacrylate (EGDMA) in propylene carbonate that contained tetraethylammonium tetrafluoroborate (TEATFB), changing the TEATFB concentration and the MAN/EGDMA molar ratio. We characterized the obtained polymer gel electrolytes with complex impedance analysis and cyclic voltammetry, intending to apply them to electric double-layer capacitors. The ionic conductivities of the polymer gel electrolytes were dependent on the TEATFB concentration, the temperature, and particularly the crosslinking degree. The polymer gel electrolytes in this system exhibited high room-temperature conductivities (Ͼ10 Ϫ3 S/cm). Furthermore, these polymer electrolytes showed good electrochemical stability windows ranging from Ϫ4.0 to ϩ4.0 V versus Ag.

“…Recently some researchers prepared polymer electrolytes with room temperature conductivities higher than 10 −3 S/cm, which were achieved by plasticizing solid polymer electrolytes with small organic molecules such as ethylene carbonate (EC) and propylene carbonate (PC) 5–7. Chintapalli and Frech used tetraethylene glycol dimethyl ether as a plasticizer 8.…”

In order to obtain highly conductive polymer electrolytes for an electric double layer capacitor, three kinds of polymer gel electrolytes were prepared. Vinyl acetate (VAc) and methyl methacrylate (MMA) were copolymerized with divinyl adipate (DA) and ethylene glycol dimethacrylate (EGDMA), respectively, in propylene carbonate (PC) containing tetraethylammonium tetrafluoroborate (TEATFB) to form network polymer gel electrolytes. MMA was also copolymerized with butylene glycol DMA for comparison. The polymer gel electrolytes obtained were characterized by means of thermogravimetry, complex impedance analysis, and cyclic voltammetry for use in the electric double layer capacitor. The ionic conductivities of the polymer gel electrolytes were dependent on the TEATFB concentration, temperature, and crosslinking degree. The polymer gel electrolytes in the VAc-DA system exhibited higher room temperature conductivities (10 Ϫ2 S/cm) than those in the MMA-EGDMA system. Further, the polymer gel electrolytes in the VAc-DA system showed good electrochemical stability windows ranging from Ϫ4.0 to 4.0 V versus Ag. Thermal analysis revealed that the polymer gel electrolytes in both systems were stable up to 150°C.
