CRUMPLED GRAPHENE-ENCAPSULATED NANOSTRUCTURES AND LITHIUM ION BATTERY ANODES MADE THEREFROM

摘要

Capsules comprising crumpled graphene sheets that form a crumpled graphene shell encapsulating an internal cargo comprising nanostructures of a second component are provided. Also provided are anode materials for lithium ion batteries comprising the capsules, wherein the nanostructures are composed of an electrochemically active material, such as silicon.
