What is it about?
Organic materials have a high carbon content, which is the most critical factor determining a supercapacitor's ability to store electric charges. One of the agricultural wastes that can be used as a supercapacitor is cocoa peels. Cocoa peels contain hemicellulose 21.06%, cellulose 20.15%, and lignin 51.98%.

Why is it important?
The supercapacitor electrode has been synthesized using activated carbon from cocoa pods. Activated carbon was prepared by first drying the raw materials under the sunlight and followed by oven drying, pre-carbonization, milling, sieving, and chemical activation with 0.3 M and 0.4 M KOH solution.
Perspectives
I hope this article makes what people know about the use of Theobroma cacao peels, because until now with the existence of abundant waste, but its use has not been maximized and has not had a high selling value.
