Special Issue Information

Dear Colleagues,

Owing to the extensive consumption of the limited natural fossil fuels in the past decades, the sustainable development of green renewable energy sources (e.g., solar, wind, and hydraulic power) is quite urgent and necessary. In addition to the green renewable energy sources, the development of efficient and cost-effective energy storage devices is essential for the reliable transmission and distribution of electrical energy sources to the demands for a variety of applications. Especially, the electrochemical energy storage/conversion devices, including the primary batteries (such as zinc-manganese batteries, etc.), secondary batteries (such as lead-acid batteries, nickel-hydrogen batteries, lithium/sodium/zinc-ion batteries, etc.), fuel cells, metal-air batteries, supercapacitors, etc. have been undergoing rapid expansion and dominating the varieties of power sources.

Until now, transition metal-based nanomaterials (TMNs) including transition metal oxides, nitrides, carbides, sulfides, and selenides have been of interest for such devices due to their eco-friendliness, highly electrocatalytic activity, significantly enhanced kinetics, and so on. In this special issue, we will focus on the rational design of nanomaterials to efficiently address the current challenges of electrochemical energy storage/conversion devices. Particularly, the investigation of fundamental aspects and design concept of TMNs on their electrochemical properties in energy storage/conversion devices is preferred. Additionally, both review and original articles are welcome for submission.

Supercapacitors are candidates with the greatest potential for use in sustainable energy resources. Extensive research is being carried out to improve the performances of state-of-art supercapacitors to meet our increased energy demands because of huge technological innovations in various fields. The development of high-performing materials for supercapacitor components such as electrodes, electrolytes, current collectors, and separators is inevitable. To boost research in materials design and production toward supercapacitors, the up-to-date collection of recent advancements is necessary for the benefit of active researchers. This review summarizes the most recent developments of water-in-salt (WIS) and deep eutectic solvents (DES), which are considered significant electrolyte systems to advance the energy density of supercapacitors, with a focus on two-dimensional layered nanomaterials. It provides a comprehensive survey of 2D materials (graphene, MXenes, and transition-metal oxides/dichalcogenides/sulfides) employed in supercapacitors using WIS/DES electrolytes. The synthesis and characterization of various 2D materials along with their electrochemical performances in WIS and DES electrolyte systems are described. In addition, the challenges and opportunities for the next-generation supercapacitor devices are summarily discussed. Full article
