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.

硒化物常被应用于钠离子电池负极材料，具有更高可逆容量和合适的工作电位，然而，循环过程中的体积变化较大，电导率较低，限制了其实际应用。通过简单的水热反应制备了FeSe2/Ti3C2Tx复合材料作为钠离子电池负极材料。Fe2+首先与乙二胺四乙酸配位并形成螯合物，经过水热反应，Ti3C2Tx和Fe2+螯合物之间产生静电作用，合成了FeSe2/Ti3C2Tx复合材料。FeSe2/Ti3C2Tx呈开放式的“花瓣”结构，Ti3C2Tx为材料提供了强导电网络并且缓解了一定的体积膨胀。电化学测试表明：FeSe2/Ti3C2Tx电极在0.5 A/g下经过150次循环后容量达到455 mA·h/g，相同电流密度下，FeSe2电极循环100圈后的容量仅为335 mA·h/g，并且在随后的循环中容量迅速衰减，以上结果表明合理的结构设计使得FeSe2/Ti3C2Tx电极具有优异的电化学储钠性能和循环稳定性。

摘要
收起

硒化物常被应用于钠离子电池负极材料，具有更高可逆容量和合适的工作电位，然而，循环过程中的体积变化较大，电导率较低，限制了其实际应用。通过简单的水热反应制备了FeSe2/Ti3C2Tx复合材料作为钠离子电池负极材料。Fe2+首先与乙二胺四乙酸配位并形成螯合物，经过水热反应，Ti3C2Tx和Fe2+螯合物之间产生静电作用，合成了FeSe2/Ti3C2Tx复合材料。FeSe2/Ti3C2Tx呈开放式的“花瓣”结构，Ti3C2Tx为材料提供了强导电网络并且缓解了一定的体积膨胀。电化学测试表明：FeSe2/Ti3C2Tx电极在0.5 A/g下经过150次循环后容量达到455 mA·h/g，相同电流密度下，FeSe2电极循环100圈后的容量仅为335 mA·h/g，并且在随后的循环中容量迅速衰减，以上结果表明合理的结构设计使得FeSe2/Ti3C2Tx电极具有优异的电化学储钠性能和循环稳定性。

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.
