Project: In situ Electron Paramagnetic Resonance (EPR) to study supercapacitor behaviour.
Energy storage using Graphene-based Supercapacitors: Graphene, and other 2d materials, hold enormous promise as supercapacitor devices for energy storage within the electrical double-layer. One route to maximise capacitive storage is through “pseudocapacitance”, i.e. the introduction of heteroelements (N, S) or heterostructures (e.g transition metal nanoparticles) into the carbon framework. The atomic level understanding of the pseudo-capacitive process is extremely poor, hence we propose to use novel techniques such as in situ electrochemical EPR spectroscopy to understand, andmaximise, pseudo-capacitance.
