Concrete That Stores Power

ranjeet singh

MIT’s Electron-Conducting Carbon Concrete (EC³) turns ordinary concrete into a powerful energy storage system. Using carbon black and electrolytes, EC³ can act as a structural supercapacitor — storing up to 2 kWh per cubic meter, sensing stress, and even powering homes. Watch this AI-generated experiment to see how future buildings might literally power themselves.  🔬 Scientific Source & References  This video is based on publicly available research conducted by MIT and collaborators.

00:00What if the concrete around you could store electricity, powering your home like a living

00:05battery? MIT scientists developed Electron Conducting Carbon Concrete, or EC3, a new composite

00:12of cement, water, ultrafine carbon black, and electrolyte solution that turns ordinary concrete

00:19into an energy-storing material. When mixed, carbon black particles self-assemble into a

00:24fractal-like nano-network inside the cement paste. This network conducts electrons, while the

00:29electrolyte ions move through pores, creating a super-capacitor-like structure inside the concrete.

00:35With optimized organic electrolytes, one cubic meter of EC3 can store two kilowatt hours of energy,

00:42about enough to power a refrigerator for an entire day. When physical stress is applied,

00:46its electrical output fluctuates, indicating potential for self-sensing and structural

00:51health monitoring in real-time. This multifunctional concrete could one day power smart homes,

00:56charge electric vehicles from roads, and even heat sidewalks in winter.
