Demand for mobile electronics, electric vehicles, and renewable energy technologies has substantially increased the requirements placed on energy storage systems, specifically Li-ion batteries (LIBs), in terms of energy and power density, reliability, and safety. With the advent of several solid-state electrolytes (SSE) that have ionic conductivities on par with liquid organic electrolytes, solid-state Li-ion batteries (SSLBs) have attracted significant attention in industry and academia as a leading solution to address the safety and reliability challenges attributed to liquid LIB electrolytes, while maintaining comparable energy and power densities. Unfortunately, substantial improvements to SSLB performance are still needed for widespread commercialization, such as addressing fabrication issues related to poor SSE incorporation into cast electrodes and addressing high interfacial resistances, stemming primarily from interfacial reactions and lack of intimate contact. Ionogels (IG), a class of solid-electrolytes, have recently garnered interest due to their ability to be processed as a liquid, ensuring formation of a uniform, low resistance electrode/electrolyte interface throughout a cast electrode. Composed of ionic liquid electrolyte (ILE) trapped inside a solid nanoporous matrix, these systems nanoscopically behave like the trapped liquid, while macroscopically, they exhibit the mechanical and dimensional stability of the matrix material. Typically, these structures are formed by creating a homogeneous solution composed of electrolyte and matrix precursor, such as a dissolved polymer or alkoxide-derived inorganic sol. Upon processing and solidification, the electrolyte becomes trapped within the network. For oxide-based ionogels, these systems can be considered as nano-sponges, where a high degree of interconnected nanopores provide facile transport and produce sufficient capillary force to entrap the liquid. The initial liquid state permits multiple processing routes to obtain uniform depositions, such as spin coating , inkjet printing , or dip coating .
