ABSTRACTThe present report is dedicated to a study of possible ways of increasing the energy density of the supercapacitor and thus, bridging the gap between the supercapacitor and the battery. Chemical functionalization of carbon nanomaterials, such as carbon nanotubes, activated carbon cloth, and activated carbon powder used as supercapacitor electrodes as well as novel aqueous electrolytes with the electrochemical window of up to 2 V are described. The hybrid approaches to energy storage mechanism in electrochemical energy storage devices are discussed. The first experimental results on the discussed hybrid energy storage devices are presented.

The Impact

In this work, plasticized polymer electrolyte films consisting of chitosan, ammonium nitrate (NH4NO3) and glycerol for utilization in energy storage devices was presented. Various microscopic, spectroscopic and electrochemical techniques were used to characterize the concerned electrolyte and the electrical double-layer capacitor (EDLC) assembly. The nature of complexation between the polymer electrolyte components was examined via X-ray diffraction analysis. In the morphological study, field emission scanning electron microscopy (FESEM) was used to investigate the impact of glycerol as a plasticizer on the morphology of films. The polymer electrolyte (conducting membrane) was found to have a conductivity of 3.21 × 10−3 S/cm. It is indicated that the number density (n), mobility (μ) and diffusion coefficient (D) of ions are increased with the glycerol amount. The mechanism of charge storing was clarified, which implies a non-Faradaic process. The voltage window of the polymer electrolyte is 2.32 V. It was proved that the ion is responsible for charge-carrying via measuring the transference number (TNM). It was also determined that the internal resistance of the EDLC assembly lay between 39 and 50 Ω. The parameters associated with the EDLC assembly are of great importance and the specific capacitance (Cspe) was determined to be almost constant over 1 to 1000 cycles with an average of 124 F/g. Other decisive parameters were found: energy density (18 Wh/kg) and power density (2700 W/kg).

The Cost

Supercapacitors with an electric double-layer design have attracted great attention in the recent years because they are promising energy storage devices for a number of applications, particularly for portable electronics and electric automobiles. They utilize the interface between the electrode and the electrolyte to store energy, resulting in energy storage devices with high power density but low energy density compared to batteries. To improve the performance and reduce the cost, researchers have made significant progress in increasing energy density, electrode voltage, and cycle life. The increase of the energy density is considered to be achieved mainly by increasing the effective specific interface between the electrodes and the electrolyte. Various electrodes with porous structure have been attempted to increase the specific surface area. The increase of electrode voltage is realized primarily via the change of liquid electrolytes to gel, solid and composite ones. In this overview, they are summarized as solid-like electrolytes. This paper reviews the materials adopted and the processing methods developed for solid-like electrolytes, as well as the general characteristics of supercapacitors employing such electrolytes.
