摘要

这项工作研究了在行星球磨机中通过高能研磨合成的硒化铜(Cu2Se)的热稳定性、电学和热电学特性。相组成通过 X 射线粉末衍射分析和扫描电子显微镜进行了研究。通过热分析监测了机械化学合成过程中前驱体的转化和产物的稳定性。此外,还观察了电性能与产品孔隙率的关系。在 Cu2Se 的致密化过程中,采用了火花等离子烧结法制备适合热电特性分析的样品。将合成 Cu2Se 的高温热电性能与其天然类似物--矿物贝氏锰矿进行了比较,以确定其在能源转换中的潜在应用。根据研究结果,通过快速机械化学反应(5 分钟)制备的未掺杂 Cu2Se 获得了相对较高的优点系数 ZT 参数(~ 1.15,T = 770 K)。Na/NaClO4/Cu2Se 电池的循环伏安测量结果表明,机械化学合成的 Cu2Se 可用作钠离子电池的插层电极。

Transport properties of mechanochemically synthesized copper (I) selenide for potential applications in energy conversion and storage

This work studied the thermal stability, electrical, and thermoelectrical properties of copper(I) selenide, Cu2Se synthesized by high-energy milling in a planetary ball mill. The phase composition was investigated by X-ray powder diffraction analysis and scanning electron microscopy. The conversion of the precursors during mechanochemical synthesis and the stability of the product was monitored by thermal analysis. The dependence of electrical properties on the product porosity was observed. For the densification of Cu2Se, the method of spark plasma sintering was applied to prepare suitable samples for thermoelectric characterization. High-temperature thermoelectric properties of synthetic Cu2Se were compared to its natural analogue-mineral berzelianite in terms of its potential application in energy conversion. Based on the results a relatively high figure-of-merit, ZT parameter (~ 1.15, T = 770 K) was obtained for undoped Cu2Se, prepared by rapid mechanochemical reaction (5 min). Cyclic voltammetry measurements of Na/NaClO4/Cu2Se cell implied that mechanochemically synthesized Cu2Se could be used as a promising intercalation electrode for sodium-ion batteries.
