高性能红磷/碳负极材料的研究进展

Research progress on high performances red phosphorus/carbon anode materials

目前商业化石墨电极较低的理论容量和较差的倍率性能已无法满足发展需求,红磷由于具有理论容量高、资源丰富以及价格低廉等特点,近年来被作为新一代储能材料受到广泛关注,但导电性差、在充放电过程中的体积膨胀等问题阻碍了红磷在二次电池中的应用。简述了红磷在储能领域中的应用前景和需要解决的难题;介绍了红磷/碳复合材料的制备方法及其优缺点和微观结构,并分析总结在金属(锂、钠、钾)二次电池中的电化学性能;对其在未来电化学储能领域中的应用前景进行了展望。

The lower theoretical capacity and poor rate performance of the current commercial graphite electrodes can no longer meet the development needs of people. Recently, red phosphorus has been widely concerned as electrochemical materials for the next generation batteries due to high specific capacity, abundant resources and low price. However, the further applications are hindered by its poor conductivity and volume variation during cycled. In this review, we discussed the preparations, micro-structures and electrochemical storage performances, application prospect and the problems to be solved of red phosphorus/carbon composites in secondary batteries.
