Herein, we present a process whereby the ionic liquid trapped inside a nanoporous matrix is replaced with an alternative liquid electrolyte, thus demonstrating a SSLB system with highly tunable physicochemical and interfacial properties. Exchange occurs after sol incorporation into a composite electrode and solidification has occurred to ensure uniform electrode wetting and a low interfacial resistance is maintained. In this study, a spin-coated, SiO2 ionogel is exchanged with several different electrolytes to assess the degree of exchange and the effect on the cell performance. We demonstrate complete ILE (1M LiFSI PYR14TFSI) exchange for 1M LiFSI DOL/DME and 1M LiClO4 PC as verified using Raman spectroscopy and thermal gravimetric analysis (TGA). Using cells composed of LiFePO4 (LFP)/exchanged gels/Li, we demonstrate improved low temperature performance for the DOL/DME-based electrolyte and high-power performance for the carbonate-based electrolyte compared to similar cells with ionic-liquid-based ionogels. These cells have similar performance to the corresponding liquid electrolyte composed cells. In addition, we demonstrate our novel exchange process in additive manufactured (AM) cells composed of LFP/gel/LTO. The cycling of both the cast and AM cells indicate that neither process has a detrimental effect on the solid matrix and entrapment does not undesirably impact the electrochemical properties of the newly confined liquid, permitting design freedom for both composition and architecture.
