Room temperature ionic liquids are widely regarded as the most promising next-generation electrolyte for energy storage. However, their structure, which dictates a device’s ability to store electrical charge, at interfaces and under nanoconfinement remains poorly understood. By integrating cutting-edge X-ray characterization tools, advanced nanocarbon synthesis and nanofabrication, and ab initio molecular dynamics simulation, this work probed with spatial and chemical detail the structure of ionic liquids confined in carbon nanopores. This provides mechanistic understanding toward optimizing ionic liquid-solid electrode interfaces and developing design rules that could dramatically increasing capacity and charge/discharge rates of future supercapacitor devices. Nevertheless, the ability to probe ions at interfaces is also critical in other areas such as batteries, desalination, electrocatalysis, and biological and chemical sensors.
