Self-assembled hierarchical yolk–shell structured NiO@C from metal–organic frameworks with outstanding performance for lithium storage†
Abstract
A facile generic environmental strategy is employed to prepare hierarchical yolk–shell hybrid NiO@C materials viz. metal–organic frameworks. The intrinsic yolk–shell nature as well as the multi-element characteristics of active components of the unique nanostructures contributes greatly to the outstanding electrochemical performance.
