An original synthesis method for the synthesis of hydrated iron trifluoride is presented. This method, based on solvothermal process starting from iron salt and HF in alcool, is economic and simple. The electrochemical performances of the composite phase FeF3·0.33H2O/Graphitic oxide is showing enhanced capacity of 250 mAh/g at 0.05 °C. © 2016 Elsevier Masson SAS.
