Graphene aerogel supported crystalline ZnO@amorphous Zn2GeO4 core–shell hierarchical structure for lithium storage

Abstract

Fabricating a combined amorphous and crystalline hierarchical structure is a promising strategy to further improve the electrochemical performance of electrode materials, because it will provide additional opportunities for altering and manipulating the electrolyte adsorption and ion migratory dynamics in the lithium storage process. In this work, a crystalline–amorphous core–shell ZnO/Zn₂GeO₄/graphene aerogel with a three-dimensional structure has been successfully fabricated and shows enhanced stability and electrochemical performances.
