ABSTRACT
This chapter explores the recent works on the preparation of nanoclay composites and their applications in energy storage and conversion devices. The various battery components and supercapacitors devised based on varieties of nanoclay-incorporated polymer composites are extensively deliberated. Because of their significant impact on the polymer matrix when incorporated into polymer-based nanocomposites, clay minerals are an excellent choice for use as a filler in polymeric separators and Li-ion battery electrolytes, as well as their low cost, availability, eco-friendliness, and high specific surface area. Supercapacitors have emerged as the utmost leaders in energy storage due to their high capacitance, high power density, quick charging/discharging processes, and extended cycle life and are used in biomedical, antimicrobial fabrics, flexible displays, wearable electronic devices, and mobile phones. Additionally, some of the critical challenges and futural perspectives of nanoscale-based clay composites and their energy domains are also highlighted.
