The ability to achieve high surface areas with nanomaterials brought several advancements in energy storage devices and their applications in different industries. Supercapacitors, a new generation of energy storage devises, have quick charge and discharge abilities, and hold as much energy as batteries and other chemical storage devices. The present study focuses on the effects of carbon nanotubes (CNTs) inclusions in polyvinyl alcohol (PVA) electrolytes for the improved capacitance values, which may affect the lifetime, charge holding, and charging and discharging rates of the graphene nanoflake-based supercapacitors. In this research, various supercapacitors were constructed using the reduced graphene oxide nanoflakes, PVA and PVA incorporated with CNTs, and the best candidates were selected for the future considerations. The test results showed that the CNT concentrations of 0.1–1.0wt% in PVA enhanced the capacitance (charge holding capacity) and reduced the internal resistance of the electrolytes significantly. This study may open up new possibilities for the supercapacitors and other energy storage devices currently under developments.

Electric Energy Storage

A solution to the problem of increasing the efficiency of traction electric drive systems, taking into account the steady increase in electricity prices, is proposed by using storage devices. Promising types of energy storage devices are considered. A comparative analysis of the main types of batteries and supercapacitors is carried out. The description, types, and main technical characteristics of batteries and supercapacitor energy storage devices are given. The choice of the best energy storage device is justified. The technical characteristics of specific models of supercapacitors are compared and the required number of individual storage devices of different models is calculated in accordance with the supply voltage of the engine and the energy consumed by them in the acceleration mode. The supercapacitor model for forming a storage battery was selected according to the following optimality criteria: minimum mass, minimum price, and minimum number of individual capacitors.

Hands On

Several universities and colleges recently have offered courses and certificate programs for training students and returning engineers in advanced energy storage, particularly in electric energy storage technology. However, few integrated advanced energy storage laboratories have been established for educational purposes. This paper presents the design, development and implementation of an interactive and computer-controlled test system for four different electric energy storage devices (electro-mechanical flywheel, electro-chemical batteries, supercapacitor and pumped hydroelectric) that serve as a teaching-aid. These units provide hands-on experience for students with multidisciplinary backgrounds who are enrolled in the advanced energy storage courses. The developed teaching-aid not only enhances the advanced energy storage training and education, but also inspires students’ interest in the green movement of renewable energy.
