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).

► In this paper, the electrochemical performance of a new intercalate electrode material, LiMn2O4 single crystalline nanowires, in an aqueous LiNO3 solution is first studied by galvanostatic cycling.
► In addition, this ARLB is principally safe and environment friendly.
► It exhibits good cycling stability and especially it is beneficial to a high power lithium-ion battery due to its good electrochemical performance at the high C-rate.
► Therefore, it appears great potential for applications in large-scale devices comparing with other batteries such as lead acid batteries and alkaline manganese batteries.
