Enhanced rate performance of LiNi0.5Mn1.5O4 fibers synthesized by electrospinning
Abstract
Spinel LiNi0.5Mn1.5O4 (LNMO) provides a high working potential as a cathode material for lithium-ion batteries. Yet there is a phase transition from cubic to tetragonal structure in LNMO during the ~3 V charge/discharge region. To suppress the large volume change and capacity fade inherent with bulk-sized LNMO particles when discharged to below 3.0 V, one-dimensional nano-structured LNMO was prepared by an electrospinning method and a subsequent heat treatment. The well-separated nanofiber precursors combat the growth and aggregation of LNMO particles during the heating procedure and lead to improved capacity, better cycling stability, and improved rate capability of the final LMNO nanofibers. The as-prepared LMNO nanofibers have a diameter as thin as 50–100 nm, which is the thinnest of this kind of complex compounds that contain multi-transition metal elements produced through the electrospinning method. In coin cell tests of this material at a current density of 27 mA g-1, the initial discharge capacity was 130 mAh g-1 over a voltage range of 3.5–4.8 V and 300 mAh g-1 over a voltage range of 2.0–4.8 V.
