What is it about?
Due to their large specific surface area, layered architecture, and high degree of graphitization, amorphous activated carbon with graphitic characteristics has received a lot of interest. Herein, graphene like activated carbon was synthesized via sono-exfoliation of hazelnut shells activated carbon. An excellent energy density of 38.7 W h kg−1 and power density of 198.4 W kg−1 were displayed by a flexible supercapacitor device with sono-exfoliated activated carbon and bio-polymer electrolyte (HEC/Na2SO4), along with 89% capacitance retention after 10,000 cycles. This results indicate that sono-exfoliation is simple, economical and scalable process for producing high performance carbonaceous materials from biomass waste for energy storage applications.

Why is it important?
Superior structural, morphological and electrochemical characteristics of sono-exfoliated hazelnut shell activated carbon are appreciable for a low cost, environmentally friendly, efficient supercapacitor electrode material. According to the study, it is possible to turn waste hazelnut shells into a fantastic value-added product for supercapacitor electrode applications.
