Editorial : deep eutectic solvents/complex salts-based electrolyte for next generation rechargeable batteries

Abstract

Recent years have seen an expansion of renewable energy technologies driven by global demands for energy alongside social and environmental concerns. One of the most significant solutions, rechargeable batteries have promising features which include high capacity, energy density, rate capability, long lifetime, and cost-effectiveness. As the key component in energy storage devices, the electrolyte has had a major impact on the chemistry/electrochemistry of rechargeable batteries/cells for a number of reasons. These include its potential window, which limits the redox potential of an electrochemical reaction. Its electrochemical activity and conductivity also influence the electrochemical reaction and consequently the battery performance. The composition, as well as the stability, of rechargeable batteries, shapes the electrolyte-electrode interface. Furthermore, its corrosivity cannot be neglected. For these reasons, researchers are highly motivated toward breakthroughs in battery performance, exploring the fundamental properties of electrolytes based on novel formulation/synthesis. Hence, this special issue of Deep Eutectic Solvents/Complex Salts Based Electrolyte for Next Generation Rechargeable Batteries focuses on the effects of electrolytes on the electrochemistry/chemistry of rechargeable batteries and cells.
