黄铜矿及其复合材料在电化学储能领域的研究进展

黄铜矿(CuFeS₂)是一种具有特殊金色光泽的天然矿物，具有四方结构，其中Fe、Cu离子与晶格中的硫形成四面体配位，相较于其他硫化物和其相对应的氧化物，CuFeS₂具有较高的电导率和优异的电化学性能，且拥有成本低廉、存在天然矿物且自然储量丰富、无毒等优势，使其具有应用于电化学储能体系电极材料的潜能。本文详细介绍了CuFeS₂的物理化学性质、几种简单的不同形貌的合成方法以及其作为电化学储能电极材料方面的研究，并对CuFeS₂材料未来的研究方向进行了展望。

Research progress of chalcopyrite CuFeS2 and its composites in the field of electric energy storage

CuFeS₂ is a natural mineral with a special golden luster and has a quadripartite structure in which Fe and Cu ions form tetrahedral coordination with sulfur in the lattice. CuFeS₂ has high electrical conductivity and excellent electrochemical properties compared to other sulfides and their corresponding oxides. With the merits of low cost, the existence of natural minerals and rich natural reserves, non-toxicity, etc., CuFeS₂ is a potential candidate for electric energy storage materials. In this paper, the physical and chemical properties of CuFeS₂, several simple synthesis methods of different morphologies, and their use as electrode materials for electric energy storage systems are introduced in detail. The current research results are summarized, and the future research direction of CuFeS₂ materials is prospected.
