“…[41] For CoP@NC/GO composites, the slopes of peak 1 and peak 2 oblique lines values are 0.737 and 0.711, respectively (Figure 6b), hinting that the lithium reaction process is controlled by diffusion and capacitancemixed behaviors. Further analysis of CV and quantitative determination of capacitance contribution are based on the following equation [42][43][44]…”

“…A decrease in total N (Table S2) is observed to decrease with increase reaction temperature, which is due to the loss of less stable pyridinic-N and pyrrolic-N species accompanying with transformation into graphitic-N. [25] For Fe/Fe 3 C@NCNT-750 and Fe/Fe 3 C@NCNT-850, we observed that both pyridinic-N have a positive shift attributed to the replacement of protons by the Fe ion withdrawing effect and the formation of FeÀN x during the pyrolysis process. [25] Figure 3d shows the high resolution XPS spectrum of Fe 2p in Fe/Fe 3 C@NCNT-750, which is deconvoluted into six peaks of Fe 0 2p 3/2 (706.8 eV), Fe 2 + 2p 3/2 (707.9 eV), Fe 3 + 2p 3/2 (711.2 eV), Fe 2 + 2p 1/2 (719.6 eV), Fe 3 + 2p 1/2 (720.1 eV) and a satellite peak (715.2 eV), from which we could deduce that iron atoms in the catalyst are either in the metallic, oxidized, or carbide state. [26] There was no Fe 0 2p 3/2 peak of Fe 3 O 4 @NCNT-650, implying only Fe 3 O 4 served as the main composition according with XRD results.…”

“…As an inert and high molecular fluoropolymer with a high dielectric constant, mechanical properties, thermal stability, corrosion resistance, and other interesting features, PVDF is widely applied in numerous fields such as tactile sensors, infrared imaging devices, actuators, electrolytic gated transistors, and the like. [38][39][40] In addition, PVDF has a reasonable Young's modulus and can act as a soft and deformable elastomer to form a buffered matrix that improves the mechanical stability [41][42][43][44] and to alleviate the volume changes of SiO x active material during the cycling process. The 3D SiO x -based flexible self-supporting membrane anodes show an extremely high specific capacity and cycling stability, which can be used as an energy source for flexible electronic devices.…”
