Electrochemical Performance of Co3O4 Nanofibers As Anode Material for Lithium-Ion Batteries

Abstract Nanostructuring is a promising approach to the problems of low diffusion coefficient of transition metal oxides anodes. Co 3 O 4 nanofibers electrode materials were successfully synthesized by electrospinning followed by controlled pyrolysis. Electrode materials based on Co 3 O 4 nanofibers applied as anode for lithium-ion batteries (LIBs) show high discharge-charge specific capacity of 595 and 527 mA h g –1 at 0.5C, respectively. Further electrochemical investigation reveals that Co 3 O 4 nanofibers exhibiting high specific capacity (300 mA h g −1 at 0.5C after 200 cycles), the capacity fading is only 11.8% after 200 cycles. Further electrochemical studies reveal that these excellent electrochemical properties should be attribute to the ordered ions diffusion pathway originated from the one-dimensional nanostructure and continuous fibrous network structure. These results revealed that the Co 3 O 4 nanofibers are promising anode materials for LIBs.
