“…As a result, negative ions move towards the positively charged electrode. Similarly, the positive ions in the electrolyte experience a solid and attractive force from the negatively charged electrode 43 . As a result, positive ions move towards the negatively charged electrode, as shown in Figure 2.…”

“…When we charge a capacitor, positive charges induce one plate and negative charges on the other, forming an electric field. Because of this, field polarization of the dielectric occurs, so its molecules align in the opposite direction in the applied field and reduce its strength which is responsible for the storage of charge on the plates in minimum Voltage [43][44] .…”

A next-generation technology, the Supercapacitor, has emerged with the potential to enable significant advances in energy storage. Supercapacitors are governed by the same fundamental equations as conventional capacitors but utilize higher surface area electrodes and thinner dielectrics to achieve greater capacitances. The existing review addresses a brief overview of the history, principles, and theory of operation of supercapacitors, along with various models, and significantly in current energy saving and storage. Here, a concise description of technologies and working principles of different materials utilized for supercapacitors has been provided. The main focus has been on materials like carbon-based nanomaterials, metal oxides, and conducting polymers. The performance of nanocomposites has been analyzed by parameters like energy, capacitance, power, cyclic performance, and rate capability. The use of supercapacitors in various applications is cited, and their advantages over alternative technologies are considered.

“…Recently there has been a growing interest in energy harvesting from mechanical systems executing vibrations [13]. In harvesting systems, some part of mechanical energy is converted into electrical energy by means of special energy subsystems [4,5] and is saved in capacitors [6] or rechargeable batteries. The energy conversion is realized by using linear DC motors or piezoelectric devices.…”

“…Between the lower platform and the intermediate platform, the LA25 linear motor (8) is placed as a part of the energy harvesting system. The workstation is additionally providedwith incremental heads, which are linear encoders(2)and(6). The displacement transmitters were selected in order to achieve a high measuring resolution of 0.01 mm for platforms(3) and(5), and 0.1 mm for platform(9).…”

In the paper, the energy harvesting from vibration of two-degree-of-freedom mechanical system is analyzed. The considered system consists of two mass linked in series by means of springs and dampers. The kinematic excitation of the system was assumed. The energy conversion system was placed in the suspension of lower mass. As a result of the analysis, the methods to increase the energy harvesting from vibration were proposed. The laboratory stand has been built and a series of measurements performed. Results of numerical simulations and measurements are presented in graphs.

Modeling of a carbon nanotube ultracapacitor

The modeling of carbon nanotube ultracapacitor (CNU) performance based on the simulation of electrolyte ion motion between the cathode and the anode is described. Using a molecular dynamics (MD) approach, the equilibrium positions of the electrode charges interacting through the Coulomb potential are determined, which in turn yield the equipotential surface and electric field associated with the capacitor. With an applied ac voltage, the current is computed based on the nanotube and electrolyte particle distribution and interaction, resulting in the frequency-dependent impedance Z(ω). From the current and impedance profiles, the Nyquist and cyclic voltammetry (CV) plots are then extracted. The results of these calculations compare well with existing experimental data. A lumped-element equivalent circuit for the CNU is proposed and the impedance computed from this circuit correlates well with the simulated and measured impedances.
