LiMn2O4 hollow nanoarchitecture was synthesized by a facile hydrothermal reaction.The as-synthesized porous LiMn2O4 exhibits pure phase with high crystalline quality.When the LiMn2O4 nanoarchitecture was used as cathode electrode,it demonstrated excellent electrochemical performance:the specific capacity is as high as 138 mAh g-1 at 0.2 C,retaining 99*,%of the initial reversible capacity after 50 cycles;the high-rate capacity even up to 10 C is as large as 80 mAh g-1.The durable high-rate capability was attributed to the unique hollow nanostructure which gave rise to fast Li-intercalation kinetics and good structural stability for the spinel electrodes.The beneficial gained from hollow nanoarchitecture may enlighten the design and construction of new spinel-based electrode for energy storage applications.
