An original synthesis method for the synthesis of hydrated iron trifluorides is presented for the first time. This method, based on solvothermal process starting from iron salt and HF in alcool, is economic, simple and environmentally benign. The electrochemical performances of the composite phase FeF3·0.5H2O/graphene is showing enhanced capacity of 200 mAh/g at C/20. © 2016 Elsevier B.V. All rights reserved.
