Résumé de la vidéo

Electronic conductivity is a key factor in achieving fast charging and high-power performance of electrical energy storage devices. The ‘beyond graphene’ march led to the discovery of new types of conductive 2D materials, like MXenes, produced by wet chemical or electrochemical extraction of interleaved ‘A’ atomic layers from the layered ternary carbide or nitride precursors.

This presentation will describe the potential use of MXenes in electrochemical capacitors. Ion transport 2D gallery spaces, redox chemistry at the transition metal oxide-like surface and metallic conductivity provided by electrons of the transition metals, make MXenes promising as candidates for high-rate energy storage applications. The ability of MXenes to spontaneously intercalate a variety of cations, while promoting fast charge transfer rates, endorses them for hybrid metal-ion capacitor applications. The use of MXenes to replace polymer binders and metal current collectors will also be addressed.

ISEECap 2019

ISEECap 2019 (International Symposium on Enhanced Electrochemical Capacitors) gathered the most renowned international experts together with students and non-specialist engineers and researchers who share interest in electrochemical capacitors. A broad range of topics was covered, including electrochemical double layer capacitors, pseudocapacitive materials and related mechanisms, electrolytes and interfaces, modelling of phenomena and systems, microsupercapacitors and related components, systems integration and applications, fast charging battery electrodes for asymmetric and hybrid devices, characterization techniques, in-situ and operando methods. This edition celebrated the ten-year anniversary of the symposium series in the beautiful city of Nantes from 6th May to 10th May 2019.
