WebOct 1, 2024 · 摘要 硬碳是最有前途的钠离子电池（SIBs）负极材料之一。然而，由于不可石墨化结构导致其导电性不足是提高其在器件中的容量和倍率性能的主要障碍。为了解决这个问题，这里通过碳化碳纳米管负载的 3-氨基苯酚-甲醛树脂球来制备碳纳米管 (CNTs) 连接的硬碳球 (HCSs) 复合材料。 WebAn investigation of the structure of carbons of different origin treated at temperatures between 1000 and 3000°C has shown that the graphitizing and non-graphitizing carbons form two distinct and well-defined classes. The differences in structure are ...

Graphitizing and non-graphitizing carbons (alternatively graphitizable and non-graphitizable carbon) are the two categories of carbon produced by pyrolysis of organic materials. Rosalind Franklin first identified them in a 1951 paper in Proceedings of the Royal Society. In this paper, she defined graphitizing carbons as those that can transform into crystalline graphite by being heated to 3000°C, while non-graphitizing carbons don't transform into graphite at any temperature.
