Abstract

La présente invention divulgue un procédé de préparation dun matériau danode en carbone dur et son utilisation. Lamidon est mélangé avec de la nano-silice, le mélange obtenu est traité thermiquement à une température allant de 150°C à 240°C sous une atmosphère inerte, le premier produit fritté obtenu est traité thermiquement à une température allant de 180°C à 220°C sous une atmosphère contenant de loxygène, le deuxième produit fritté est séparé de manière cyclonique pour éliminer la nano-silice afin dobtenir des microsphères préoxydées à base damidon, et les microsphères préoxydées à base damidon subissent un traitement de carbonisation sous une atmosphère inerte pour obtenir le matériau danode en carbone dur. Dans la présente invention, les particules de silice peuvent être adsorbées sur la surface de la matière première damidon, et la réticulation se produit entre les chaînes moléculaires damidon au cours du processus de traitement thermique, et sous la barrière du dioxyde de silicium, les particules damidon ne seront pas réticulées mais fusionnées pour former une structure sphérique. Lintroduction datomes doxygène au cours du processus de préoxydation produit une lacune doxygène et augmente les sites actifs pour le stockage dions sodium après la carbonisation, augmentant ainsi la capacité réversible des batteries au sodium-ion.
