영문 초록

In this study, active material for supercapacitor is synthesized employing electronic heated tobacco wastes. Compared with the conventional tobacco, heated tobacco left more wastes due to its heating rather burning. Herein, we introduce an effective method for recycling of heated tobacco wastes and developing supercapacitor active materials. In detail, the electronic heated tobacco waste (eHT-W) are carbonized under nitrogen atmosphere with various temperatures of 800, 850 and 950 ︒ C. Resulting eHT-W material carbonized at 850 ︒ C (eHT-W/850) exhibited the highest specific capacitance owing to the high carbon-to-oxygen ratio of 6.1 and the low ID/IG ratio of 1.36. To further enhance the capacitance, polypyrrole(PPy) is deposited onto eHT-W/850 material. (eHT-W/850@PPy) Finally, asymmetric supercapacitor device is assembled with eHT-W/850 and eHT-W/850@PPy as negative and positive electrodes. As-prepared asymmetric supercapacitor device successfully enlightned the red LED, indicating the remarkable specific capacitance and operating voltage of 2.0 V.
