Abstract: | Single crystalline cubic spinel LiMn2O4 nanowires were synthesized by hydrothermal method and the precursor calcinations. The phase structures and morphologies were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and high-resolution transmission electron microscopy (HRTEM). Galvanostatic charging/discharging cycles of as-prepared LiMn2O4 nanowires were performed in an aqueous LiNO3 solution. The initial discharge capacity of LiMn2O4 nanowires was 110 mAh g−1, and the discharge capacity was still above 100 mAh g−1 after 56 cycles at 10C-rate, and then 72 mAh g−1 was registered after 130 cycles. This is the first report of a successful use of single crystalline spinel LiMn2O4 nanowire as cathode material for the aqueous rechargeable lithium battery (ARLB). |
