▎ 摘  要

By a rational design and facile vacuum filtration, a flexible and free-standing LiFePO4/carbon nanotube/reduced graphene oxide film electrode is fabricated for lithium-ion batteries. The carbon nanotube and reduced graphene oxide substrates are favor of improving the conductivity of the electrode; meanwhile, the LiFePO4 particles can efficiently reduce aggregation between carbon nanotube and reduced graphene oxide. The resultant self-supporting LiFePO4/carbon nanotube/reduced graphene oxide electrode delivers excellent electrochemical performance beyond the metal-base electrode. After 100 cycles at 0.2 C, the capacity maintains 151 mAh g(-1), nearly staying the same with initial value. Especially, at 10 C, the specific capacity still keeps 98 mAh g(-1). Moreover, these findings in this work supply a means of manufacturing LiFePO4 electrode and urge the practical application of LiFePO4 in flexible facilities.
