Synthesis and electrochemical properties of Fe2WO6

Fe2WO6 structure belongs to the tri-alpha-PbO2 and crystallizes in orthorhombic symmetry. The crystal structure is fabricated of FeO6 or WO6 octahedra distributing edges analogous to the c-axis. Fe2WO6 was prepared via trouble-free solid state reaction method. Fe2WO6 structure and its electrochemical behaviour were measured via various characterization techniques. The redox couples of Fe3+/2+, W6+/5+ W5+/4+, and the tri-alpha-PbO2 structure inspire us to study Fe2WO6 as fascinating anode material. The primary discharge capacity was 206 mAh/g which analogous to the insertion of 3.0Li. It exposed a capacity of 82 mAh/g subsequent to 25 cycles. (C) 2020 The Authors. Published by Elsevier Ltd.
