▎ 摘  要

NOVELTY - Nano hollow tin (IV) oxide graphene anode material comprises amino graphene aerogel, zinc chloride, tin tetrachloride and sodium hydroxide at mass ratio of 0.5-4:10:20-22:60-90. USE - The nano hollow tin (IV) oxide graphene anode material is used for lithium ion battery (claimed). ADVANTAGE - The tin (IV) oxide is uniformly loaded on the surface of graphene oxide which exposes large number of electrochemical active sites. The hollow structure is conducive to the process of lithium ion removal and embedding and reduces volume expansion of anode materials. The graphene forms three-dimensional conductive network between nano tin (IV) oxide interfaces which improves conductivity of anode materials.
