Abstract

We developed an environmentally friendly, one-pot, solution-based method to synthesize a FePO4·H2O/carbon nanotube coaxial nanocomposite for lithium ion battery applications without using multi-step, time-consuming processes or hazardous reaction media. The resulting nanocomposite delivered a discharge capacity of 157 mAh g-1 at a current density of 12.5 mA g-1, 146 mAh g-1 at 625 mA g-1 and 61 mAh g-1 even at 15,000 mA g-1. The excellent high rate capability was attributed to the improved electronic conductivity due to the intimate contact between nano-structured FePO 4·H2O and CNT, and to the easy access of the electrolyte because of the porous structure of the FePO4· H2O.
