One Step Solid State Synthesis Of Fef3 Center Dot 0.33h(2)O/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 233.9mAhg−1 at a current density of 20mAg−1 within potential range 1.8–4.5V 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.
