摘要
在减少碳排放实现碳中和的新能源发展背景下,以锂离子电池为代表的动力电池被赋予更高期望,探索开发满足高容量、高倍率和高稳定性的新材料已然成为发展关键。石墨负极和硅碳负极目前发展较为成熟,并保持着各自优势。黑磷作为新型储能材料,依靠自身二维层状结构和较高的锂化电位,展现出在实现超快充电方面的突出优势,但也存在体积膨胀等问题。针对黑磷负极存在的问题,研究者们从各维度进行优化研究,包括结构优化、表界面优化以及预锂化策略。本文首先从各角度综合论证了黑磷可以作为超快充电锂离子电池负极的可能性,进而综述了针对黑磷负极的优化进展,并提出自己的观点和建议,指出黑磷负极面临的挑战和发展方向,展望了黑磷负极的发展前景。
In the context of the development of new energy sources to reduce carbon emissions and achieve carbon neutralization,power batteries represented by lithium-ion batteries are given higher expectations.The development of electrode materials with high capacity,high multiplicity and high stability is a key step to achieve this goal.Graphite cathodes and silicon carbon cathodes are relatively mature at present,and maintain their respective advantages.Black phosphorus has two-dimensional layered structure and high lithium potential,which shows outstanding advantages in realizing extremely fast charging,but there are also some problems such as volume expansion.In view of the problems of black phosphorus anode,researchers studied the optimization from various dimensions,including structure optimization,surface interface optimization and the pre-lithiation strategy.In this paper,the possibility that black phosphorus can be used as anode electrode of extremely fast charging lithium ion battery is demonstrated,the optimization progress of black phosphorus negative electrode is then reviewed,and its own views and suggestions are put forward.The challenges and development direction of black phosphorus anode electrode are pointed out,and the development prospect of black phosphorus anode electrode is prospected.
