Correlation Between Microstructure and Na Storage Behavior in Hard Carbon
Biao Zhang,Biao Zhang,Camelia Matei Ghimbeu,Christel Laberty,Christel Laberty,Cathie Vix-Guterl,Jean-Marie Tarascon +6 more
TL;DR: In this article, a single voltage Na uptake plateau at similar or equal to 0.1 V with a capacity of 200 mAh g(-1) for CNFs carbonized at above 2000 degrees C. This specific performance may be nested in the higher degree of graphitization, lower active surface area, and different porous texture of the carbon nanofibers.
Journal ArticleDOI
Realistic molecular model of kerogen's nanostructure
Colin Bousige,Camelia Matei Ghimbeu,Cathie Vix-Guterl,Andrew E. Pomerantz,Assiya Suleimenova,Gavin Vaughan,Gaston Garbarino,Mikhail Feygenson,Christoph Wildgruber,Franz-Josef Ulm,Roland J.-M. Pellenq,Roland J.-M. Pellenq,Roland J.-M. Pellenq,Benoit Coasne,Benoit Coasne +14 more
TL;DR: A panel of realistic molecular models of mature and immature kerogens are proposed that provide a detailed picture of kerogen's nanostructure without considering the presence of clays and other minerals in shales and show that they predict essential features amenable to experimental validation.
Journal ArticleDOI
Insights on the Na+ ion storage mechanism in hard carbon: Discrimination between the porosity, surface functional groups and defects
Camelia Matei Ghimbeu,Camelia Matei Ghimbeu,Joanna Górka,Virginie Simone,Loïc Simonin,Sebastien Martinet,Cathie Vix-Guterl,Cathie Vix-Guterl +7 more
TL;DR: In this article, the authors employed N2, Kr and CO2 gases to correctly assess the changes in hard carbon porosity induced by different pyrolysis temperature of cellulose.
Journal ArticleDOI
Vanadium nitride/carbon nanotube nanocomposites as electrodes for supercapacitors
Camelia Matei Ghimbeu,Encarnacion Raymundo-Piñero,Philippe Fioux,François Béguin,Cathie Vix-Guterl +4 more
TL;DR: In this article, vanadium nitride/multiwalled carbon nanotubes (VN/CNTs) composites for pseudo-capacitor applications were obtained via the sol-gel synthesis of organic or inorganic vanadium oxide precursors followed by temperature programmed ammonia reduction.
