• ZnMn2O4 nanofibers were successfully synthesized by a facile electrospinning and calcination method for lithium-ion batteries.
• The as-prepared ZnMn2O4 nanofibers, containing PVP and PAN with ratio of 1:9, exhibited a high initial discharge capacity of 1274 mAh g−1, and the stabilized capacity was as high as 603 mAh g−1 after 60 cycles at a current density of 50 mA g−1.
• The as-prepared ZnMn2O4 anode material showed good lithium storage performances and excellent rate capability and can be a promising electrode material for lithium-ion batteries in the future.

In this paper, ZnMn2O4 nanofibers were synthesized by a facile electrospinning and calcination method. Electrochemical properties of the nanofiber anode material for lithium-ion batteries were investigated. The as-prepared ZnMn2O4 nanofibers, containing PVP and PAN with ratio of 1:9, exhibited a high initial discharge capacity of 1274 mAh g−1, and the stabilized capacity was as high as 603 mAh g−1 after 60 cycles at a current density of 50 mA g−1. Besides the high specific capacity and good cyclability, the electrode also showed good rate capability. Even at 2000 mA g−1, the electrode could deliver a capacity of as high as 352 mAh g−1. The results suggest a promising application of the electrospun ZnMn2O4 nanofibers as anode material for lithium-ion batteries.
