Supercapacitors have emerged as a prominent area of research in energy storage technology, primarily because of their high power density and notable stability compared to batteries. However, their practical implementation is hindered by their low energy densities and insufficient long‐term stability. In this study, bulk porous Nb4N5 and Ta3N5 single crystals with excellent pseudocapacitance and electrical conductivity are successfully prepared by solid‐phase transformation method. These monolithic porous single crystals (PSC) exhibit a long‐range ordered crystalline architecture and substantial specific surface area, which facilitate rapid charge transport and ion diffusion within the electrolyte‐permeated crystal lattice. Notably, the areal capacitance of the porous Nb4N5 single crystals is 12.9 F cm−2 at a current density of 6 mA cm−2 and 35.08 F cm−2 at a scan rate of 1 mV s−1. Furthermore, the energy density reached 1.79 mWh cm−2 at a power density of 20 mW cm−2, demonstrating their high energy storage capability. Moreover, these porous Nb4N5 single crystals exhibited robust capacitance retention and exceptional cycling stability, making them promising candidates for use as electrodes in energy storage applications. These results underscore the significant potential of porous metal nitride single crystals in advancing the field of capacitive energy storage.

A zeolitic imidazolate framework (ZIF‐9) was synthesized via solvothermal reaction using cobalt (Co) salt and benzimidazole ligands in the presence of polyacrylonitrile. The precursor was electrospun to form carbon nanofibers (CNFs) creating freestanding, binder‐free supercapacitor electrodes. Polyvinylpyrrolidone (PVP) and NaCl were added to the precursor solution to reduce fiber diameter and improve structural integrity during high‐temperature annealing. The Co/CNF sample achieved an areal capacitance of 316 mF cm−2 and an energy density of 0.043 mWh cm−2 at a current density of 1 mA cm−2. The addition of NaCl and PVP reduced fiber diameter by 30% and increased capacitance by 3.6 times. The optimal sample maintained 96.2% of its capacitance over 10,000 charge/discharge cycles, demonstrating strong electrochemical stability. Symmetrical pouch cells with the developed electrodes powered a light‐emitting diode and a humidity/temperature sensor, demonstrating their potential in portable electronics.
