By studying the transport behavior of a relatively simple electrolyte in idealized slit pores, this work lays the foundation for developing a comprehensive, predictive understanding of transport in more complex nanoconfined electrolytes. Future work will explore the effect of surface chemistry on confined ion transport, from the impact of the electronic structure of the pore wall to the role of defects and functional groups, as well as specific ion effects and the behavior of mixed electrolyte solutions. Such efforts will be instrumental in design-ing optimized nanoconfined environments that enable fast and selective ion transport for applications in energy storage and separations technologies.
