While silicon-based negative electrode materials have been extensively studied, to develop high capacity lithium-ion batteries (LIBs), implementing a large-scale production method that can be easily transferred to industry, has been a crucial challenge. Here, a scalable wet-jet milling method was developed to prepare a silicon-graphene hybrid material to be used as negative electrode in LIBs. This synthesized composite, when used as an anode in lithium cells, demonstrated high Li ion storage capacity, long cycling stability and high-rate capability. In particular, the electrode exhibited a reversible discharge capacity exceeding 1763 mAh g −1 after 450 cycles with a capacity retention of 98% and a coulombic efficiency of 99.85% (with a current density of 358 mA g −1 ). This significantly supersedes the performance of a Si-dominant electrode structures. The capacity fade rate after 450 cycles was only 0.005% per cycle in the 0.05–1 V range. This superior electr...

锂离子电池高容量阳极湿式喷射研磨合成层状硅-石墨烯异质结构

尽管已经对硅基负极材料进行了广泛的研究，但要开发高容量锂离子电池（LIB），实现可轻松转移到工业中的大规模生产方法，这一直是一项严峻的挑战。在这里，开发了可扩展的湿式喷射研磨方法，以制备用作LIB负极的硅-石墨烯杂化材料。当用作锂电池的阳极时，这种合成的复合材料显示出高的锂离子存储容量，长的循环稳定性和高倍率能力。特别地，电极在450次循环后表现出超过1763mAh g -1的可逆放电容量，容量保持率为98％，库伦效率为99.85％（电流密度为358mA g -1）。这大大取代了以硅为主的电极结构的性能。在450个循环之后，在0.05-1 V范围内，每个循环的容量衰减率仅为0.005％。这位优秀的电气工...
