In this study, the impact of morphology of conductive agent and anode material (FeO) on lithium storage properties was throughly investigated. Granular and belt-like FeO active materials were separately blended with two kinds of conductive agents (i.e., granular acetylene black and multi-walled carbon nanotube) as anodes in lithium-ion batteries (LIBs), respectively. It was found that the morphology of conductive agent is of utmost importance in determining LIBs storage properties. In contrast, not as the way we anticipated, the morphology of anode material merely plays a subordinate role in their electrochemical performances. Further, the morphology-matching principle of electrode materials was discussed so as to render their utilization more rational and effective in LIBs.
在本研究中,深入探究了导电剂和负极材料(FeO)的形态对锂存储性能的影响。分别将颗粒状和带状的FeO活性材料与两种导电剂(即颗粒状乙炔黑和多壁碳纳米管)作为锂离子电池(LIBs)的负极进行混合。结果发现,导电剂的形态在决定LIBs存储性能方面至关重要。相比之下,与我们预期的不同,负极材料的形态在其电化学性能中仅起次要作用。此外,还讨论了电极材料的形态匹配原则,以便使其在LIBs中的利用更加合理和有效。
