ABSTRACT

Recycling hazardous polymers into polymeric products of high commercial value in the field of energy storage is a challenge, where redox-active electrodes are to be fabricated. The carbonization of waste polymers in a controlled manner, however, converts them into better-quality and upgraded carbon-based nanomaterials. Supercapacitors have become a promising attraction due to their superior electrochemical performance with enhanced cyclic life and rapid storage capacity. This chapter reviews the recent advances and challenges associated with the fabrication of cost-effective and best supercapacitors potentially by disposing of polymeric waste to great value carbon-based nanomaterials. A number of synthetic methods are also reviewed, which are used to transform polymeric waste into carbon material for supercapacitor applications. Recycling saves more energy as compared to the manufacturing of new material. It offers sustainable development and finds a solution to the energy crisis by transforming the trash into high-voltage supercapacitors and has thus become a future trend.
