Mesoporous single-crystalline MnOx nanofibers@graphene for ultra-high rate and long-life lithium-ion battery anodes

We report a novel strategy for the spatial confinement of mesoporous single-crystalline MnO_x nanofibers within a graphene shell (PSCMnO_x@G). The PSCMnO_x@G exhibits ultra-high rate performance (1072 mA h g⁻¹ at 0.1 A g⁻¹ and 419 mA h g⁻¹ at 10 A g⁻¹) and excellent cycling stability.
