Scientists at MIT have made a groundbreaking discovery that could revolutionize energy storage: electrified cement. By combining cement, water, and carbon black, researchers have created a conductive nanocomposite that acts as a supercapacitor, capable of storing and releasing electrical energy.
The key to this discovery lies in the clumping together of carbon black particles within the voids of the reacting cement. These clumps form wiry tendrils that greatly enhance conductivity. With the addition of an electrolyte material like potassium chloride, the cement becomes a powerful energy-storing superstar. Currently, the capacity of these cement capacitors is relatively small, only able to power a few LED light bulbs. However, the potential for scaling up the process is enormous. The materials required are inexpensive and abundant, making it accessible for widespread use. Imagine building foundations made of this electrified cement, capable of storing enough energy to power an entire house for a day. Renewable energy sources like solar or wind could supply the energy stored in the cement, creating a sustainable power solution.
But the application doesn't stop there. The concept of electrified cement opens up possibilities for roads that can power electric vehicles as they drive over them. While there are challenges to overcome, such as storage capacity and structural strength, researchers are already exploring this idea for future implementation. In their published paper, the MIT researchers state that "these structural concrete-like supercapacitors could be employed for bulk energy storage in both residential and industrial applications." This means that self-sustaining shelters, self-charging roads, and even intermittent energy storage for wind turbines could become a reality.
