Title

Vertically aligned carbon nanotubes based materials for High Energy Hybrid ultracapacitors

Abstract

The aerosol CVD (Chemical Vapor Deposition) method provides dense carpets of aligned carbon nanotubes (CNT) which applications are particularly promising in the field of nanocomposites combining aligned nanotubes and electronically conductive polymer (ECP) developed for the electrochemical storage of energy in ionic liquid media. In the H2E-CAP ANR project in collaboration with the University of Cergy (LPPI), Tours (PCM2E) and an 'end user' industrial partner we will develop the controlled growth of aligned CNTs on substrates of interest for the development of supercapacitors electrodes involving aligned CNTs and PCE or metal oxides. The objective of the project is to synthesize aligned CNTs carpets on metal using a newly developed laboratory process consisting of the pre- deposition of a ceramic layer at the substrate surface before the CNTs growth stage. In a second step we will evaluate the possibility to deposit PCE and metal oxides by different routes with the ultimate goal to extend the process to large surface. These new nanostructured electrodes will be associated with symmetric or asymmetric configuration in order to improve the performance of electrochemical hybrid supercapacitors in terms of energy density and power.
