            This research turns agricultural waste — specifically pineapple stem starch — into a valuable material for energy storage devices. Instead of using expensive or non-renewable materials, the researchers used this natural waste to make carbon that can store electricity efficiently. The carbon material, created through a simple chemical process, has many tiny pores and a very large surface area, allowing it to store and release electrical energy quickly. It also works well for a long time, keeping about 91% of its performance even after 12,000 charge–discharge cycles. Because the material is low-cost, sustainable, and easy to produce, it could be a great alternative for making durable and high-performance electrodes in supercapacitors and other energy storage systems.
