Abstract

Due to its semi-metallic properties, layered structure, and the unique electronic properties endowed by the large interlayer spacing, bismuth-based materials exhibit a wide range of application scenarios in the electrochemical application direction. Currently, the unclear multiphase phase transition mechanism of bismuth-based materials and the capacity attenuation caused by the volume expansion resulting from the phase transition restrict their development. The storage mechanisms of different ions vary significantly across various application scenarios. In this study, we have conducted a classified discussion on the differentiated energy storage mechanisms for cations and anions in bismuth-based materials (such as cation/anion-specific conversion reactions), and have extended their application scope to emerging fields such as capacitive deionization. Exploring the application research of bismuth-based materials in new electrochemical technologies is of great significance, which provides new inspiration and insights for the further development of bismuth-based materials.

铋基材料：从电化学储能到新型电化学分离技术

铋基材料由于其半金属性质、层状结构以及层间距大所赋予的独特电子性能，在电化学应用方向上呈现出广泛的应用场景。目前，铋基材料多相相变机理不明确，相变引起体积膨胀导致容量衰减，制约了铋基材料的发展。在不同的应用场景下，不同离子的储存机制差异很大。在本研究中，我们对铋基材料中阳离子和阴离子的差异化储能机制（如阳离子/阴离子特异性转化反应）进行了分类讨论，并将其应用范围扩展到电容性去离子等新兴领域。探索铋基材料在电化学新技术中的应用研究具有重要意义，为铋基材料的进一步发展提供了新的启示和见解。
