Hollow CoFe2O4 nanospheres comprising tube-in-tube structured nanofibers and GC layers are formed by pitch-derived carbon; these have improved structural stability and electrical conductivity resulting in excellent cycling and characteristics. Tube-in-tube structured nanofibers consisting of hollow CoFe2O4@GC nanospheres showed excellent long-cycle performance (682 mA h g-1 for the 1400th cycle at a high current density of 3.0 A g-1) and excellent rate capability (355 mA h g-1) even at an extremely high current density of 50 A g-1.In thi
