The ever-increasing demand for energy has driven the development of energy-storage technologies to go beyond Li-ion batteries. As a consequence, a plethora of advanced energy storage technologies have emerged in recent years, for instance Li-S, Na-air, and Zn-air, as well as other flexible/wearable supercapacitors. Li-S batteries promise ultra-high energy density (e.g., many-fold higher than that of commercial Li-ion batteries), while the next-generation supercapacitors offer improved performance with additional functionality and could be a potential contender for future energy intensive applications.
This themed collection compiles recent research and review articles focused mainly on electrochemical energy storage using batteries, i.e., post Li-ion batteries, and flexible/wearable supercapacitors beyond H-ion and Li-ion. These reports show that the high performance energy storage solutions are urgently required to satisfy the growing demand for portable energy. We hope that this themed collection will provide valuable information to the readers, and could help to drive future developments in the field of energy storage.
