EMIM TFSI confined in nanoporous carbons for supercapacitor double layer structure investigation

Abstract: To reach net-zero emission goals, there is a need for a range of new technologies to form the infrastructure for storing the energy harnessed by renewable energy sources such as wind and solar power. Supercapacitors are devices with high power density capabilities, providing a complementary usage to batteries, which are commonly known for their very high energy density. The main theories underpinning our understanding of capacitors are based on 2-dimensional models, whereas the materials commonly investigated for use in supercapacitors are carbon materials with 3-dimensional networks of pores. To better understand this system, we wish to investigate the structure of the ionic liquid 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-TFSI) confined within the pores of 4 different carbon materials: YP50, cmk-3 and a two carbon fibre-derived powders. By investigating a system with no solvent molecules, the simulation to perform EPSR on will be simpler, and we hope to better resolve the arrangements of the ions in the pores.
