摘要：

Ultrathin LiMn2O4 nanowtres with cubic spinet structure were synthesized by using a solvothermal reaction to produce alpha-MnO2 nanowire followed by solid-state lit-Nation. LiMn2O4 nanowires have diameters less than 10 nm and lengths of several micrometers Galvanostatic battery testing showed that LiMn2O4 nanowires deliver 100 and 78 mAh/g at very high rate (60C and 150C, respectively) in a larger potential window with very good capacity retention and outstanding structural stability Such performances are due to both the favorable morphology and the high crystallinity of nanowires
