Selenides have a higher reversible capacity and a suitable working potential. However, their large volume change during cycling and low conductivity restrict their practical applications. In this paper, FeSe2/Ti3C2Tx composites were synthesized as anode materials for sodium-ion batteries by a simple hydrothermal method. Fe2+ were firstly coordinated with ethylene diamine tetraacetie acid to form chelates, and then FeSe2/Ti3C2Tx composites were synthesized via the electrostatic interaction between Ti3C2Tx and Fe2+ chelates after the hydrothermal reaction. FeSe2/Ti3C2Tx has an open 'flower petal' structure, and Ti3C2Tx in the composite provides an intense conductive network for the material and relieves volume expansion. According to the results of the electrochemical test, Ti3C2Tx electrode has a capacity of 455 mA·h/g after 150 cycles at 0.5 A/g, while the capacity of FeSe2 electrode at the same current density is only 335 mA·h/g after 100 cycles, and the capacity decays rapidly in the subsequent cycles. It is indicated that FeSe2/Ti3C2Tx electrode has superior electrochemical sodium storage performance and cycling stability.
