Title:
CARBON NANOSHEET-BASED SODIUM-ION BATTERY NEGATIVE ELECTRODE MATERIAL, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/093189
Kind Code:
A1
Abstract:
A carbon nanosheet-based sodium-ion battery negative electrode material, and a preparation method therefor and an application thereof. The sodium-ion battery negative electrode material is graphene oxide @CeO2/carbon nanosheet. The preparation method comprises: firstly, adhering CeO2 to the carbon nanosheet; and then wrapping the outer layer with graphene oxide, so that CeO2 is located between the carbon nanosheet and the graphene oxide.
