Microwave-assisted fluorolytic sol–gel route to iron fluoride nanoparticles for Li-Ion batteries

A simple microwave-assisted fluorolytic sol–gel synthesis of 30 nm sized FeF3 nanocrystals supported on partially reduced graphene oxide is reported. The as-fabricated nanostructures used as positive electrodes in Li-ion batteries show capacity retention as high as 150 mA h g−1 even after having sustained repeated charge–discharge cycles.
