Spinel LiMn<sub>2</sub>O<sub>4</sub> Nanorods via Template–Engaged Method and as Cathode Materials for Li-Ion Batteries

Spinel LiMn 2 O 4 nanorods were prepared by a hydrothermal method followed by solid-state lithiation. The produce β-MnO 2 nanowire as template, and LiOH·H 2 O was used as lithium source. The spinel LiMn 2 O 4 nanorods samples were characterized by SEM, XRD, (HR)TEM, and galvanostatic charge/discharge profile measurement. Compared with the LiMn 2 O 4 nanoparticles, the LiMn 2 O 4 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).
