Two-dimensional (2D) materials are widely used in various applications due to their extraordinary properties. In particular, their electrochemical stability, low electrical resistance, and huge specific surface area make them very interesting active materials for supercapacitors. Herein, flexible, biodegradable, and low-cost supercapacitors are introduced in a very simple way based on hand-drawing pencil traces or -rubbing molybdenum disulfide (MoS2), titanium trisulfide (TiS3) and franckeite traces on the paper. Results demonstrate that pencil-drawn paper has higher capacitance performance (
