Abstract:
Super capacitor is an important device for energy storage and usage with high power and high efficiency. Commercial super capacitors are typically fabricated by using binder to attach electrode powder to the metal foil current collector. In this paper, we present a method to fabricate super capacitors using binder-free electrodes and carbon current collector to enhance the compact size, light weight and flexibility. To obtain high power and high energy density, nano composite electrode of CNTs-polyaniline was employed. The super capacitors with PVA electrolyte achieved the electrode capacitanc

Abstract:
Activated carbon fibers(ACFs) were prepared from general pitch-based carbon fiber by steam activation and catalytic activation method, respectively. The surface area and pore structure of the resultant ACFs were analyzed by N2 adsorption, and electrochemical performances as electrodes of super capacitors were characterized by galvanostatic, cyclic voltammograms and AC impedance spectrum analysis. The results show that ACFs prepared by both methods have similar BET surface area, while their pore size and distribution are different. Compared with steam activation, catalytic activation results in

Abstract:
A new fundamental principle of the theory of dielectrics in capacitors is demonstrated. That is, dielectric material in any geometry that reduces the field generated by charges on capacitor electrodes is effective in increasing capacitance. Specifically, it is shown that super dielectric material on the outer surfaces of the electrodes of a parallel plate capacitor increases dielectric constant, as well as energy and power densities, by orders of magnitude. The implicit assumption in all current capacitor theory, that the “capacitor” is only that region occupied by the electrodes and the space

Abstract:
Supercapacitors (SCs) are a form of energy storage that fills the vacuum left by traditional capacitors and batteries. They have greater energy storage capacity than capacitors and can deliver electricity at higher rates than batteries. Both the capacitor and supercapacitor have two electrodes (plates) separated by a dielectric, however super capacitors have electrodes with a larger surface area and thinner dielectrics, allowing for higher energy densities. Super capacitors are extensively employed in portable electronic devices due to its high storage capacity. The design, properties, and use

Abstract:
The focus of this thesis has been to determine the usable voltage range of carbon-based supercapacitors (SC). Supercapacitors are a relatively new type of capacitors with a vast increase in capacitance compared to capacitors which utilize a dielectric as charge separator. A SC consists of two electrodes and an electrolyte separating the electrodes. The charges are stored by electrostatic forces in the interface between the electrode and the electrolyte, forming the so called electrochemical double-layer (EDL). With porous electrodes the effective surface area of the interfacial zone can be mad

Abstract:
Energy storage systems have recently become absolutely necessary for day-to-day existence because of energy issues. Super capacitors are among the most significant forms of energy storage devices. Supercapacitors rely on electrodes to store and release energy. Electrodes and electrolytes are crucial components that play an essential role in the performance and efficiency of the supercapacitor. Hence, for better super capacitor performance, choosing the appropriate components is of utmost importance as well. In order to understand their functionality and potential applications, various factors like their energy density, power density, and capacitance are considered. The sorts of supercapacitors, their electrodes, and their taxonomy, as well as electrolytes and the variables affecting specific capacitance, are briefly studied in the current study. It includes an extensive discussion of the importance of transition metal oxides, their doping, and their composites. Additionally, studying these components can provide insights into their efficiency and durability, allowing for improvements in their design and performance. This paper provides an overview of certain significant electrodes, their characteristics, and the electrolyte behavior affecting a specific capacitance.

Piezoelectric materials have many applications including sensors, actuators, and motors. However, the ability of piezoelectric films to generate electricity from wind power has only recently been advanced. Piezoelectric films harvest wind energy by means of a layer of polyvinylidene fluoride (PVDF) that upon deformation generates an internal electrical voltage across two silver-ink electrodes. These films are allowed to freely flap in an airflow to cause deformation and thus electricity generation.
