Abstract:

The use of nonrenewable fossil fuels for energy has increased in recent decades, posing a serious threat to human life. As a result, it is critical to build environmentally friendly and low-cost reliable and renewable energy storage solutions. The supercapacitor is a future energy device because of its higher power density and outstanding cyclic stability with a quick charge and discharge process. Supercapacitors, on the other hand, have a lower energy density than regular batteries. It is well known that the electrochemical characteristic of supercapacitors is strongly dependent on electrode

Abstract:

A supercapacitor is a type of electrical component that has larger capacitance, due to asymmetric behavior with better power density, and lower ESR (effective series resistance) than conventional energy-storage components. Supercapacitors can be used with battery technology to create an effective energy storage system due to their qualities and precise characterization. Studies have shown that the use of quantum dots as electrodes in supercapacitors can significantly increase their effectiveness. In this research article, we have used a Drude model based on free electrons (asymmetric nature) t

Abstract:

In this paper, thermal model of the symmetric rectangular stackable supercapacitors are established. By using the finite element method, the temperature distribution of the supercapacitor is simulated. Then the supercapacitor's thermal behavior under the ambient temperature, but with different current density is analyzed. The simulation results show that the maximum temperature during the discharge process occurs in the center of the supercapacitor. The maximum temperature is associated with the applied current, and the higher the applied current is, the higher the maximum temperature is. It's

Abstract:

The research on supercapacitors has been attractive due to their large power density, fast charge/discharge speed and long lifespan. The electrode materials for supercapacitors are thus intensively investigated to improve the electrochemical performances. Various transition metal layered double hydroxides (LDHs) with a hydrotalcite-like structure have been developed to be promising electrode materials. Earth-abundant metal hydroxides are very suitable electrode materials due to the low cost and high specific capacity. This is a review paper on NiMn LDHs for supercapacitor application. We focus

Abstract Smart devices that are portable and wearable have advanced significantly over the years. Further research on compatible storage devices with tiny, light and flexible properties is required to make wearable electronic devices more versatile, lightweight, smart, and commercially viable.

Despite the growing popularity of supercapacitors (supercondensers), the common model of discharge and the unified method of describing their characteristics are not available as of yet. This is explained by the complexity of the physical and chemical processes occurring there. This work provides an analysis of the charge/discharge curves for a laboratory-manufactured and an industrial supercapacitor. It has been shown that a two-step discharge mechanism is typical for the supercapacitors under study, unlike for usual capacitors, and time constants differ by approximately one order of magnitud
