The method (201) comprises the steps of rolling the exfoliated graphite (101) using rolling instrument (103) to form an EG sheet (104). In-situ coating is done on EG sheet (104) to form flexible EG or polymer electrode which is used to make supercapacitors (106). A graphite powder (101) is added with the mixture of HNO3 and H2SO4 in the ratio of 1:3 resulting in oxidized graphite. Oxidized graphite undergoes thermal shock in an isothermal furnace at a temperature of 900 degree Celsius for time duration of 2 minutes resulting in EG worms (102).
