Published: March 1, 2024

Abstract Among the total 17 UN‐SDGs (sustainable development goals) proposed by United Nations, goal 7 basically ensures easy global availability of sustainable, clean, cost effective, reliable, and modern energy. Researchers are primarily concentrating on renewable energy sources in this direction since they environmentally friendly. But there numerous obstacles, such as their low reliability, irregular nature, remote availability, so forth, that prevent them from being widely used commercial applications. Combining these with effective affordable storage technologies can be a promising solution to approach concerns including rising consumption, reliable consistent electric power, better grid stability. Modern systems double layer capacitor (EDLC) lithium‐ion batteries have great deal potential for wide range Carbon‐derived materials most flexible fundamental conversion Since it requires pyrolysis activation expensive starting like wood, petroleum, coal, commercially produced activated carbon is costly unsustainable. Due rapidly increasing amount plastic waste requirement sustainable development, plastics into valuable yet inexpensive nanomaterials attracted significant research interest. Their outstanding capability charge accumulation transportation due enormous surface area, high chemical stability, electrical conductivity combination density. The present article examines necessity efforts undertaken develop supercapacitors Li‐ion devices using recycled plastic.
