Two-dimensional black phosphorus (2D BP), an emerging material, has aroused tremendous interest once discovered. This is due to the fact that it integrates unprecedented properties of other 2D materials, such as tunable bandgap structures, outstanding electrochemical properties, anisotropic mechanical, thermodynamic, and photoelectric properties, making it of great research value in many fields. The emergence of 2D BP has greatly promoted the development of electrochemical energy storage devices, especially lithium-ion batteries. However, in the application of 2D BP, there are still some problems to be solved urgently, such as the difficulty in the synthesis of large-scale high-quality phosphorene, poor environmental stability, and the volume expansion as electrode materials. Herein, according to the latest research progress of 2D BP in the field of energy storage, we systematically summarize and compare the preparation methods of phosphorene and discuss the basic structure and properties of BP, especially the environmental instability and passivation techniques. In particular, the practical application and challenges of 2D BP as anode material for lithium-ion batteries are analyzed in detail. Finally, some personal perspectives on the future development and challenges of BP are presented.
二维黑磷（2D BP）作为一种新兴材料，一经发现便引起了极大的关注。这是因为它兼具了其他二维材料前所未有的特性，如可调节的带隙结构、出色的电化学性能、各向异性的机械、热力学和光电性能，使其在许多领域具有巨大的研究价值。二维黑磷的出现极大地推动了电化学储能器件的发展，尤其是锂离子电池。然而，在二维黑磷的应用中，仍有一些亟待解决的问题，如大规模高质量磷烯的合成困难、环境稳定性差以及作为电极材料时的体积膨胀等。在此，根据二维黑磷在储能领域的最新研究进展，我们系统地总结和比较了磷烯的制备方法，并讨论了黑磷的基本结构和性能，特别是环境不稳定性和钝化技术。尤其详细分析了二维黑磷作为锂离子电池负极材料的实际应用和挑战。最后，对黑磷未来的发展和挑战提出了一些个人观点。
