Publication date: Available online 15 April 2019Source: Journal of Industrial and Engineering ChemistryAuthor(s): Juan Du, Lei Liu, Yifeng Yu, Yue Zhang, Aibing ChenAbstractA self-assembly method using ionic liquids as soft-template and nitrogen precursor, resin as carbon precursor, silica as assistant agent, mesoporous resin spheres as additive, is employed to prepare N-doped core-shell mesoporous sphere and carbon sheet composite (N-CMCS/CS). The obtained N-CMCS/CS possesses thin sheet, core-shell spheres, dual-mesoporous structure, large specific area and a certain of N-doping, which endows it with superior electrochemical performance as electrode material in supercapacitor.Graphical abstractA novel N-doped core-shell mesoporous carbon sphere and sheet composite with a high specific capacitance and excellent energy density in supercapactor, which employed Ionic liquid as template, phenolic resin as carbon precursor, TEOS as assistant agent and mesoporous resin spheres as additive for the formation of the flaky/spherical hybrid structure.
