Simulate graphene-based EDLC charge/discharge cycles and explore energy storage frontiers
🤔 What Is a Graphene Supercapacitor?
A graphene supercapacitor stores energy by accumulating ions at the surface of graphene electrodes, forming an electric double layer (EDLC). Unlike batteries that rely on slow chemical reactions, supercapacitors charge and discharge in seconds by purely electrostatic means. Graphene's extraordinary surface area (2,630 m²/g) and conductivity make it the ideal electrode material — imagine a sheet of carbon just one atom thick that can hold a lightning bolt's worth of charge.
Why does this matter? Modern electronics need energy storage that charges instantly, lasts millions of cycles, and delivers bursts of power on demand. Graphene supercapacitors bridge the gap between batteries (high energy) and conventional capacitors (high power), enabling regenerative braking in EVs, grid-scale energy buffering, and wearable devices that charge in seconds instead of hours.
