Spinel LiMn₂O₄ Nanorods via Template–Engaged Method and as Cathode Materials for Li-Ion Batteries

Abstract:

Spinel LiMn₂O₄ nanorods were prepared by a hydrothermal method followed by solid-state lithiation. The produce β-MnO₂ nanowire as template, and LiOH·H₂O was used as lithium source. The spinel LiMn₂O₄nanorods samples were characterized by SEM, XRD, (HR)TEM, and galvanostatic charge/discharge profile measurement. Compared with the LiMn₂O₄nanoparticles, the LiMn₂O₄ nanorods showed superior cycling stability, better rate capability, good high temperature performance, and delivered a discharge capacity of 122 mAh/g (at 1 C, 100 cycles).
