Abstract
- Nano-engineering graphene-based composite anodes have motivated broad investigations of the high energy density lithium-ion batteries. Here, a sandwich-like and porous NiCo 2 O 4 @reduced graphene oxide (rGO) nanocomposite was presented. Through an incipient dipping process, the NiCo 2 O 4 precursors attach on the rGO densely, which significantly improves the material loading of the NiCo 2 O 4 @rGO composites. Serving as an anode of the lithium-ion battery, the NiCo 2 O 4 @rGO composites exhibit an unprecedented capacity of 1566 mAh g −1 cycling at a current density of 1000 mA g −1 over 700 times; while a capacity of 886 mAh g −1 at 100 mA g −1 over 100 cycles was achieved upon a NiCo 2 O 4 @rGO//LiCoO 2 full-cell, which indicates a promising potential for high energy density battery applications.
