The ability to exchange electrolytes into a solution-processable, pseudo-solid electrolyte exemplified here offers a unique solution to address fabrication or performance issues typically associated with ionogels or solid-electrolytes, while providing an opportunity to tailor the electrolyte properties to suit the application. Though the exchange process increases the fabrication cost and time, it provides an innovative way to create an electrolyte for custom applications that traditionally has been challenging, such as the complex architectures or extreme conditions required by the aerospace industry . From a fundamental standpoint, the process provides an opportunity to investigate the interaction of the same porous matrix with different electrolytes and potentially design systems with emergent behaviors. This technique's novelty is best demonstrated by the representative AM cell. The use of an AM process allows the creation of complex designed cells where the incorporation with most solid electrolytes is infeasible. Due to the flexibility of the additive manufacturing and solvent exchange processes, many other custom shapes can be realized that could not be achieved using conventional liquid electrolytes and separators. Multidimensional batteries, an approach to improve volumetric and areal energy and power, represent one such area of interest as the electrolyte's fabrication process and performance has traditionally been the limiting factors. Though only the DOL/DME and PC systems were demonstrated in this study, we believe that this process is ubiquitous for most commonly used electrolytes due to the high solubility of most organic solvents in ionic liquids and due to the silica matrix's mechanical and chemical stability. The pyrrolidinium system was used here for comparison of the electrochemical performance, but more feasible scaling could be achieved by replacing it with a cheaper, less viscous, aprotic ionic liquid. Similarly, while LFP and LTO were used as exemplar electrode materials, ionogels have been demonstrated to be stable or modifiable for a range of different lithium chemistries. The solvent-exchange approach presented here for improving ionogel electrolytes represents a facile method to tailor the electrochemical properties of a solution-processable solid electrolyte. This enables improved compatibility and performance for a wide range of chemistries, environmental conditions, and geometries. While limited here to LIBs, our approach presents a novel platform with implications beyond LIBs, such as for neuromorphic computing , other ion electrochemicalstorage-systems , or fundamental analysis of electrolyte confinement effects .
