Fabrication of electrospun ZnMn2O4 nanofibers as anode material for lithium-ion batteries
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. (C) 2015 Elsevier Ltd. All rights reserved.
