Chapter 9: Bioactive and Biodegradable Supercapacitors: Recent Advances, Challenges, and Future Perspectives

The development of biocompatible and biodegradable supercapacitors for energy storage is crucial. Rapid progress in the field of hybrid, flexible, and wearable device applications is ushering in this era of smart technologies. The development of devices that function according to industry requirements in a biological context is difficult. Current energy storage systems lack flexibility, and are made using toxic electrolytes and harsh reaction conditions. Researchers are currently working on a novel project that uses biopolymers, conducting polymers, and only electrode materials derived from wood to create fully organic devices that are environmentally friendly. There are many reports on biodegradable supercapacitors that are sustainable and are promising to replace the current conventional technologies including batteries that are made up of toxic and corrosive materials. Herein, the chapter describes the application of biodegradable electrode materials in energy storage device fabrication. The work focuses on recent research progress in this field along with major challenges and future perspectives.
