Special Issue Information

Dear Colleagues,

Advanced batteries play a significant role in the global market for electric vehicles and portable electronic gadgets. They are also expected to be crucial in future technology for sustainable energy. Additionally, efficient and affordable energy storage systems are urgent on the basis of renewable energy sources as well as the increasing number of electric vehicles and electronic gadgets. In order to meet the future needs for energy storage, sustainable and novel material systems with high energy densities, readily available raw materials, and safety are required. Additionally, investigations of new types of battery materials that are sustainable, environmentally friendly, high-energy-density, and lightweight are essential to advance such technologies. In line with this, the cell performance, enhanced safety, and monitoring management of this technology are also essential in terms of practical applications.

In this Special Issue, we encourage authors and invite all forms of contributions (full papers, communications, and perspectives) in sustainable energy storage and conversion systems, metal-ion, metal-air battery, and redox flow battery technologies, and supercapacitors. Topics can range from advanced materials innovation, fabrication, interfacial phenomena and reaction kinetics and mechanisms to new design and characterizations, safety issues, and the recycling of materials. Both basic and applied research on energy storage technologies in experimental or computational/theoretical methods is welcome.

Supercapacitors have attracted attention as efficient energy storage systems owing to their high power density and cycling stability. The use of appropriate electrode materials is important for high-performance supercapacitors, and various carbon materials have been studied as supercapacitor electrodes. In this study, carbon nanofibers with high specific surface areas were fabricated via a simple electrospinning process. Carbon nanofibers were fabricated by adjusting the ratio of polyacrylonitrile (PAN) to bisphenol A (BPA) and evaluated as electrode materials for supercapacitors. With the addition of BPA, improved specific surface area and oxygen functional groups were observed compared with nanofibers using only PAN. Therefore, BPA3, which had the highest specific surface area, exhibited a 28% improvement in capacitance (162 F/g) compared with BPA0 fabricated using only PAN. Carbon nanofibers fabricated by adjusting the ratio of BPA to PAN are promising electrodes for supercapacitors owing to their high capacitance and stability. Full article

Climate change is forcing action to reduce energy consumption and greenhouse gas emissions. An extremely important area of high-polluting energy consumption is material transport and, within this, the transport of chilled goods, including deep-frozen goods, is an important contributor. Phase change materials (PCMs) can have an important role in reducing energy consumption for the transport of chilled goods, but the current state of knowledge is not sufficient to bring the solution into popular use. This article includes a study of the effect of implementing microencapsulated PCM (mPCM) in polyurethane foam (PU) on the insulation performance of refrigerated trailer walls in low-temperature transport. In this research, mPCM was used, characterised by a phase-change heat in the range of 170–195 kJkg and a phase change temperature in the range from −10 °C to −9 °C. The studies performed show the potential of using mPCMs to improve the insulation performance of the walls of refrigerated trailers. Containing mPCM in the amount of 5.0% wt. placed throughout the entire volume of the wall can improve thermal conductivity of the wall for up to 15% in peak and 4.5% (0.2792 Wm2K without mPCM and 0.2665 Wm2K with mPCM) in the phase change temperature range. Out of the range of phase change temperatures, the thermal conductivity of the wall with mPCM is worse for 2.72% than in walls without PCM. Problems that need to be tackled were also identified, before the solution can be put into everyday use, i.e., finding the technology to increase the proportion of mPCMs relative to PU. Full article
