This article discusses the urgency of developing efficient energy storage devices to reduce CO2 emissions in urban transportation, with a focus on the importance of solid electrolytes and their application in electric vehicles. By constructing solid polymer electrolytes based on epoxy resins, combining titania nanoparticles and ionic liquid, promising solid electrolytes with good mechanical properties can be obtained.
Nowadays, there is a great environmental urgency in finding new and more efficient alternatives to reduce CO2 and other greenhouse gases emissions in urban mobility. The development of high-performance energy storage devices is a key breakpoint in making this possible. All the efforts are addressed in obtaining efficient energy storage devices and for this a solid electrolyte becomes indispensable. For urban safety in electrical vehicles (EVs), their resistance and mechanical properties are as important as energy storage capability. In this article we developed solid polymer electrolytes (SPEs) based on epoxy resins and their hardeners, ionic liquid, lithium salt and/or titania nanoparticles. We studied the dynamic curing by DSC and determined the activation energies and curing enthalpies for the solids. The optimized SPE, combining titania nanoparticles and ionic liquid, showed promising mechanical properties (T-g > 70 degrees C and storage modulus at 30 degrees C > 1 GPa).
