Title (EN) MULTI-LAYERED GRAPHENE MATERIAL HAVING A PLURALITY OF YOLK/SHELL STRUCTURES
(FR) MATÉRIAU EN GRAPHÈNE MULTICOUCHE COMPORTANT UNE PLURALITÉ DE STRUCTURES DE TYPE JAUNE D’ŒUF/COQUILLE
Abstract:
(EN) Multi-layered graphene materials and methods of making and using the same are described herein. A multi-layered graphene material can include at least two graphene layers that are attached to one another and have a plurality of yolk-shell type structures retained within a plurality of spaces between the graphene layers. Each yolk/shell type structure can include an elemental sulfur nano- or microstructure yolk and a carbon-containing porous shell. The yolk-shell structure has a volume sufficient to allow for volume expansion of the elemental sulfur nano or microstructure without deforming the multi-layered graphene structure.
(FR) La présente invention concerne des matériaux en graphène multicouches et des procédés de fabrication et d'utilisation de ceux-ci. Un matériau en graphène multicouche peut comprendre au moins deux couches de graphène qui sont attachées l'une à l'autre et ont une pluralité de structures de type jaune d’œuf/coquille retenues dans une pluralité d'espaces entre les couches de graphène. Chaque structure de type jaune d’œuf/coquille peut comprendre un jaune de nano- ou microstructure de soufre élémentaire et une coquille poreuse contenant du carbone. La structure de type jaune d’œuf/coquille a un volume suffisant pour permettre une expansion de volume de la nano- ou microstructure de soufre élémentaire sans déformer la structure de graphène multicouche.
