MIT and Harvard University researchers have developed a new material by mixing cement, water, and carbon black.
This special cement can function as a giant supercapacitor, storing and releasing electrical energy much faster than traditional batteries. The combination of cement and carbon black forms a conductive nanocomposite, allowing the cement to act like wires and increase its conductivity.
The cement becomes a powerful energy storage device by adding a standard electrolyte material.
Although the current prototypes are small, the researchers believe this technology could be scaled up for larger applications, such as building foundations and roads that can store energy and powerhouses or electric vehicles. This innovation opens up possibilities for more efficient and sustainable energy storage in the future.
