One step solid state synthesis of FeF3·0.33H2O/C nano-composite as cathode material for lithium-ion batteries

Nanometer-sized FeF3·0.33H2O/acetylene black composite has been synthesized by one step chemico-mechanical ball-milling process using Fe (NO3)3∙9H2O and NH4F as precursors and investigated as cathode materials for secondary lithium batteries. The obtained FeF3·0.33H2O/C composite was described in terms of structure, morphology, and electro-chemical performance. The composite exhibited a noticeable capacity of 233.9 mAh g−1 at a current density of 20 mA g−1 within potential range 1.8–4.5 V and good rate capability. These results showed that FeF3·0.33H2O/C nano-composite prepared from an easily scalable chemico-mechanical ball-milling process was of great industrial interest.
