Abstract
Electrochemical energy storage systems are crucial components for the realization of a carbon-neutral/carbon-negative energy sector globally. Industrial applications require energy storage technologies that cater to a wide range of specifications in terms of form factor, gravimetric and volumetric energy density, charging rates, and safety, among others. The key electrochemical technologies for industrial applications are supercapacitors and batteries. Supercapacitors are high-power devices while batteries typically cater to high energy density requirements. This chapter provides an in-depth understanding of these technologies in terms of materials, processing, working principle, and architecture. Subsequently, state-of-the-art of these technologies is discussed with an emphasis on materials, manufacturing, and end-use systems. Finally, emerging technologies in the electrochemical energy storage field are highlighted.
