MIT's new supercapacitor material is formed by mixing cheap carbon black with cement and water, making it viable for commercial building use.

The material can form plates capable of lighting LEDs, which might find applications in energy storage for roads and buildings. But there are still challenges facing the team, as ensuring that the plates are able to keep both their energy-storing capability and structural strength is complicated. While black carbon has greater energy-storing properties, using more of it can weaken the concrete. The researchers believe using 10 percent black carbon in the mix provides the best balance. However, more can be used in scenarios where structural strength isn’t so critical.
