Two-dimensional (2D) structured black arsenic phosphorus (B-AsP) compound materials play a pivotal role in a wide range of applications due to their exotic physical properties and flexible architectures. Here, 2D B-AsP compound materials were synthesized via mineralization-assisted gas phase transport. High-resolution X-ray diffraction (HRXRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were used to characterize the composition and crystal structures of the B-AsP flakes. The results show that the synthesized B-AsP has good crystallinity and composition close to the designed value. B-AsP compound materials are new materials with a high theoretical specific capacity and can be used as negative electrodes in lithium ion batteries (LIBs). These materials show a higher specific capacity in their first charge/discharge cycle than graphite. These data provide basic support for research on the energy storage capacity of B-AsP compound materials. The results have great potential for improving the performance of lithium ion batteries.

二维黑砷磷及其在锂离子电池负极中的应用
二维(2D)结构的黑色砷磷(B-AsP)复合材料由于其奇异的物理特性和灵活的结构在广泛的应用中起着关键作用。在这里,二维B-AsP复合材料是通过矿化辅助气相传输。高分辨率X射线衍射(HRXRD),拉曼光谱,X射线光电子能谱(XPS),扫描电子显微镜(SEM)和透射电子显微镜(TEM)用来表征B-的组成和晶体结构AsP薄片。结果表明,合成的B-AsP具有良好的结晶度和组成,接近设计值。B-AsP复合材料是具有较高理论比容量的新材料,可以用作锂离子电池(LIB)的负极。这些材料在其第一次充电/放电循环中显示出比石墨更高的比容量。这些数据为研究B-AsP复合材料的储能能力提供了基础支持。
