वैज्ञानिकों ने इस्तेमाल हो चुकी बैटरी से प्राप्‍त सामग्री का उपयोग करना शुरू कर दिया है: Researchers from International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous institute of the Department of Science and Technology (DST), recovered graphite from spent lithium-ion batteries and chemically exfoliated it to increase surface area and the number of edge functional groups. They also carried out extensive physicochemical characterization, electrochemical evaluation for
