One dimensional nanomaterials for energy storage application

Abstract

Material innovation and low capex manufacturing processes are required to accelerate the development and appropriation of electrochemical power sources such as batteries and super-capacitors. These devices are important not only to power the gadgets of modern life, but also to make the transition from fossil-fuels to Renewable Energy technologies and electric vehicles. Here we present the use of one dimensional core-shell structures based on nano carbon as anodes for Li-ion batteries. Modification of the highly reversible TiO₂ shell with oxides with larger theoretical capacitance was implemented to improve the performance of electrodes based on 1D‑MWCNT@TiO₂. Theoretical calculations provided a better understanding of the basic phenomena at the carbon/oxide interfaces, particularly those related to the stability of the conductive carbon core, which was found very sensitive to the symmetry and thickness of the oxide deposition.
