“…The intriguing charge storage mechanism within the ultra-small space of the fabricated PSCFS was further investigated by cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD) measurements with an operating voltage of 1.2 V. The ideal capacitive properties of the PSCFS electrode are indicated by the quasi-rectangular forms of the CV curves in Figure S8a under the stable potential window of 1.2 V. Figure S8b displays the GCD performance in an operating potential window of 1.2 V at several current densities from 0.1 to 0.2 mA cm –2 . GCD curves of the electrode exhibit symmetric behavior, which is indicative of fast charge–discharge properties and capacitive response. − The device possesses a maximum areal capacitance of 15.5 mF cm –2 at a current density of 0.1 mA cm –2 , and even at a current density of 0.2 mA cm –2 , the areal capacitance of the device is maintained at a considerable value of 9.7 mF cm –2 . The variation of areal device capacitance with applied scan rates is presented in Figure S8c, which shows that the PSCFS device exhibits an areal device capacitance of 37.6 mF cm –2 at an applied scan rate of 2 mV s –1 .…”

With the contemplations of ecological and environmental issues related to energy harvesting, piezoelectric nanogenerators (PNGs) may be an accessible, sustainable, and abundant elective wellspring of energy in the future. The PNGs’ power output, however, is dependent on the mechanical energy input, which will be intermittent if the mechanical energy is not continuous. This is a fatal flaw for electronics that need continuous power. Here, a self-charging flexible supercapacitor (PSCFS) is successfully realized that can harvest sporadic mechanical energy, convert it to electrical energy, and simultaneously store power. Initially, chemically processed multimetallic oxide, namely, copper cobalt nickel oxide (CuCoNiO4) is amalgamated within the poly(vinylidene fluoride) (PVDF) framework in different wt % to realize high-performance PNGs. The combination of CuCoNiO4 as filler creates a notable electroactive phase inside the PVDF matrix, and the composite realized by combining 1 wt % CuCoNiO4 with PVDF, coined as PNCU 1, exhibits the highest electroactive phase (>86%). Under periodic hammering (∼100 kPa), PNGs fabricated with this optimized composite film deliver an instantaneous voltage of ∼67.9 V and a current of ∼4.15 μA. Furthermore, PNG 1 is ingeniously integrated into a supercapacitor to construct PSCFS, using PNCU 1 as a separator and CuCoNiO4 nanowires on carbon cloth (CC) as the positive and negative electrodes. The self-charging behavior of the rectifier-free storage device was established under bending deformation. The PSCFS device exhibits ∼845 mV from its initial open-circuit potential ∼35 mV in ∼220 s under periodic bending of 180° at a frequency of 1 Hz. The PSCFS can power up various portable electronic appliances such as calculators, watches, and LEDs. This work offers a high-performance, self-powered device that can be used to replace bulky batteries in everyday electronic devices by harnessing mechanical energy, converting mechanical energy from its environment into electrical energy.

“…This substrate containing the composite sulfide serves as a cathode for storage analysis. 23 In addition, Ni 2 FeS 4 and Ni 2 FeS 4 -ePpy are governed by an electrodeposition and electropolymerization procedure conducted over a preactivated carbon cloth. The electrodeposition of Ni 2 FeS 4 composites onto CC was performed in an electrolyte containing nickel(II) and iron(III) nitrates in equal molar amounts (0.3 M) coupled with thioacetamide and urea to prepare a homogeneous electrolyte solution.…”

Battery-type electrode materials have recently been explored as an exclusive class of high-capacity cathode materials for the advancement of hybrid supercapacitors. The electrode materials' higher specific energy, long-term cycle stability, and faster ion transportation are commendable attributes that have prompted researchers to envisage high-performance cathode materials. The hierarchically structured electrodes provide optimal redox sites and channels for accelerating the transit of ions and electrons between the electrodes and electrolytes. Electropolymerization and a facile hydrothermal procedure followed by calcination were used to concoct Cu−Fe−Co-based trimetallic sulfide and Ni−Fe-based bimetallic sulfide with the polypyrrole composite over carbon cloth for the development of a flexible asymmetric supercapacitor. The hierarchical core−shell Cu 4 Fe 2 Co 2 S 4 hybrid composite on carbon cloth was used as a high-performance cathode material for solid-state supercapacitors. The Cu 4 Fe 2 Co 2 S 4 electrode exhibits a capacitance retention of 84.87% after 10,000 cycles and a specific capacitance of 334 mAh/g at 4 mA/cm 2 . In addition, the electropolymerized Ni 2 FeS 4 -Ppy on carbon cloth was initially reported as the recent anode, with a retention of the capacitance of 92.32% after 10,000 cycles, a specific capacitance of 1228 mAh/g at 8 mA/cm 2 , and a significantly increased specific energy of 790 Wh/kg. The ionic liquid polymer-based electrolyte gel assembled flexible all-solid-state asymmetric supercapacitor Ni 2 FeS 4 -Ppy/ PVA-DMSO-EMIM-BF 4 /Cu 4 Fe 2 Co 2 S 4 has a specific energy of 756.7 Wh/kg and specific power of 10750 W/kg, indicating a specific capacity of 352 mAh/g and remarkable retention of the capacitance of 96% after 10,000 cycles. These unrivaled inorganic−organic amalgamation systems strengthen the synergistic development of innovative functional electrode materials for energy storage applications with improved cyclic stability and rate capability.

“…23 Numerous TMOs, such as MnO 2 , Co 3 O 4 , V 2 O 5 , NiO, and SnO 2 , have been investigated widely in this respect. [24][25][26][27][28] However, these materials suffer from inherent poor electrical conductivity, which negatively affects electron transport in them. 29 It is likely that multi-metallic oxides may show a great enhancement in charge storage as they show higher electronic conductivity and may be associated with multiple oxidation states, thus leaving the possibilities of richer redox reactions compared to single-component TMOs.…”
