Multiscale Dot‐Wire‐Sheet Heterostructured Nitrogen‐Doped Carbon Dots‐Ti3C2Tx/Silk Nanofibers for High‐Performance Fiber‐Shaped Supercapacitors

“…Therefore, by balancing the ion accessible surface and electrical conductivity, the best energystorage performance is realized. To our knowledge, capacitance level of NCDs-Ti 3 C 2 T x /SNFs fiber has reached one of the largest values compared with the latest literatures, as summarized in Figure 3i and Table S1, including ZIF-L(Zn)-@Ti 3 C 2 T x (1700 F cm À 3 ), [31] Ti 3 C 2 T x /CAC (1244.6 F cm À 3 ), [37] LC pure Ti 3 C 2 T x (1265 F cm À 3 ), [40] Ti 3 C 2 T x /rGO (341 F cm À 3 ), [48] Ti 3 C 2 T x /CNT (22.7 F cm À 3 ), [49] Ti 3 C 2 T x /Aramid (807 F cm À 3 ), [50] MnO 2 @Ti 3 C 2 T x /CNT (371.1 F cm À 3 ), [51] Ti 3 C 2 T x /PEDOT : PSS (614.5 F cm À 3 ), [43] Ti 3 C 2 T x /rGO (345 F cm À 3 ), [52] shearing Ti 3 C 2 T x (1661 F cm À 3 ), [32a] O-flat Ti 3 C 2 T x (1360 F cm À 3 ), [53] Ti 3 C 2 T x (950 F cm À 3 ), [54] Ti 3 C 2 T x /CNT yarn (1083 F cm À 3 ) [14] and Ti 3 C 2 T x /GO (586.4 F cm À 3 ). [55] In order to satisfy the demands of practical application, we built solid-state asymmetric FSC.…”

Three-dimensional N-doped mesoporous carbon–MXene hybrid architecture for supercapacitor applications

“…These values far exceeded those of previously reported 2D MXene and carbonbased symmetric cells. 20,65,[69][70][71][72][73][74] The outstanding electrochemical behavior of the NMC@MXene-based cell is due to the unique architecture of interconnected MXene networks with assembled MC structures and large surface area which can confer more active sites for redox reactions and facilitate electrolyte ion diffusion, leading to the effective practical application of the active material.…”
