Abstract
The interconnected LiMn2O4 fibers have been synthesized by using easily accessible cellulose filter paper as template. SEM and TEM images indicate the fibers are porous and constructed by nano grains. Without surface modification, the fibers exhibit superior high-rate capabilities and good cycling stability. The discharge capacities at 0.5 C and 20 C are 123 and 101 mAh gâ1 respectively, and about 78.9% of its initial capacity can be retained after 1000 cycles at 5 C. The superior rate performance and excellent cyclability can be attributed to the porous fiber structure, single crystalline and exposed {111} facet.
