Abstract
Abstract Gel polymer electrolytes (GPE) composed of triethylene glycol diacetate (TEGDA)–2-propenoic acid butyl ester (BA) copolymer and commercial used liquid organic electrolyte are prepared via in situ polymerization. The ionic conductivity of the as-prepared GPE can reach 5.5 × 10 −3 S cm −1 with 6 wt% monomers and 94 wt% liquid electrolyte at 25 °C. Additionally, the temperature dependence of the ionic conductivity is consistent with an Arrhenius temperature behavior in a temperature range of 20–90 °C. Furthermore, the electrochemical stability window of the GPE is 5 V at 25 °C. A Li|GPE|(Li[Li 1/6 Ni 1/4 Mn 7/12 ]O 2 ) cell has been fabricated, which shows good charge–discharge properties and stable cycle performance compared to liquid electrolyte under the same test conditions.
