Abstract
The project aims to assess the application potential of various sp2 and sp3 hybridized carbon nanostructures as active electrodes in two energy storage systems – Li-ion and water-in-salt batteries. As sp2 hybridized carbon nanostructures, hollow graphene shells will be used, while for sp3 hybridization boron-doped diamond nanoparticles will be used. The structure and morphology of synthesized sp2/sp3 carbon nanostructures will be investigated using TEM, SEM, Raman spectroscopy and XPS. Cyclic voltammetry, electrochemical impedance spectroscopy, and charging/discharging tests will be performed for all prepared energy storage systems.
