Mn3O4 embedded 3D multi-heteroatom codoped carbon sheets/carbon foams composites for high-performance flexible supercapacitors

In this work, a kind of novel Mn3O4 embedded 3D N/P-codoped carbon sheets/carbon foams (Mn3O4–NPCN/CF) composites is directly prepared by high-temperature pyrolysis. The Mn3O4–NPCN/CF with highly opened porous structure has outstanding advantages, such as providing abundant channels for ion fast transport, increasing electrolyte permeation rate, ensuring effective contact between electrode and electrolyte, and enhancing electron conduction.
