Energy storage by electrochemical systems has gained an unparalleled relevance during the last few decades. In particular, there has literally been an outburst of interest in the area of electrochemical capacitors (ECs) under the strong influence of diverse applications in industrial and consumer electronics, electric transportation, and the renewable electricity sector. New markets and application requirements are challenging the current technology of ECs, asking for the development of advanced devices with outstanding characteristics in terms of specific energy and/or power. The search and development of new, modified, composite, and hybrid electrode materials; the enhanced control over pore texture and architecture of the active electrode layer; the investigation of novel electrolytes; the design and exploration of asymmetric and hybrid system configurations; and the recent trend towards all solid state devices are all research directions pursued actively towards unprecedented solutions for electrochemical energy storage.
Capacitive deionization (CDI) is a water treatment technology sharing with electrochemical capacitors the fundamental principle of electrosorption at the double layer of high surface area carbon electrodes to remove ions from water streams. Material research in CDI has explored different strategies to improve the salt adsorption capacity of the electrodes, aiming primarily at extending the capability of CDI to the treatment of concentrated solutions and eventually to seawater desalination, as either a self-standing or a complementary technology. Research in this area is still in its infancy, though the list of emerging electrode materials for CDI already includes a range of carbon materials, including functionalized activated carbon, tailored porosity carbon, and nanocarbon materials. Surface charge modification by functionalization, hybridization with oxides, ion intercalating oxides, and even compounds undergoing reversible faradaic reaction are other approaches that have been attempted, initiating a new fascinating field of research.
This Special Issue aims to collect original contributions focusing on recent advances in material research and exploring new concept materials for electrochemical capacitive storage and deionization. The topics of interest include the following:
- Nanocarbon, hybrid, and composite materials for electrochemical capacitors (ECs);
- Synthesis, characterization, and application of pseudocapacitive and battery-like materials;
- Metal oxides and nitrides in ECs;
- Conducting polymers in ECs;
- Electrolytes development, including solid-state electrolytes;
