Graphene-scroll-sheathed α-MnS coaxial nanocables embedded in N, S Co-doped graphene foam as 3D hierarchically ordered electrodes for enhanced lithium storage

A 3D hierarchically ordered transition-metal-sulfides-based electrode configuration is designed by engineering N, S co-doped graphene foam with embedded ultra-long graphene-scrolls-sheathed α-MnS coaxial nanocables. Benefiting from the unique structural merits, the resulted electrode shows remarkably enhanced lithium storage properties.269
