聚丙烯腈基碳纳米纤维闭孔形成与界面微环境调控机制研究：面向高效储钠
Revisiting the Closed‐Pore Formation and Interfacial Micro‐Environment Modulation Mechanisms of Polyacrylonitrile‐Derived Carbon Nanofibers Toward Efficient Sodium Storage
模型导读
聚丙烯腈基碳纳米纤维在1400°C最优热解温度下经"拉链式"点-线-面固相融合，实现层间距、闭孔与3D导电骨架的协同平衡，GCNFs-1400首次库仑效率达96.2%。醚基电解液相比酯基电解液更利于形成更薄、更均匀且化学稳定的SEI膜。材料微结构与界面微环境的双重调控，使该材料在无预钠化钠离子电池和钠离子电容器中展现出优异的倍率性能与长期稳定性。
