Cement and soot help store energy?

Published: Updated: Estimated reading time: 2 minutes

Scientists at MIT have successfully created a composite material by combining cement with carbon black. This innovative technology holds significant promise in the field of energy storage, particularly for harnessing energy from unpredictable renewable sources.

The reliance on finite resources in current energy storage technologies highlights the urgency of exploring novel and eco-friendly alternatives.

Composite supercapacitors

The innovative nanocomposite that emerges from combining soot and cement offers a remarkable application in the construction of supercapacitors. Cement serves as a robust hardener, while carbon black exhibits conductor-like qualities.

When water triggers the reaction of cement, it generates an interconnected network of voids. The carbon content moves into these open spaces, forming wire-shaped structures. Consequently, a substantial surface area is achieved within a confined volume.

To prepare the material for use, it is immersed in an electrolyte (such as potassium chloride). This process facilitates the accumulation of charged particles on the carbon structures. The resulting composite electrodes form a supercapacitor, which can be likened to the poles of traditional batteries.

When linked to a power source, the composite panels store energy, and when connected to a load, they release it rapidly. This mechanism enables efficient energy storage and quick release akin to the function of batteries.

Innovative EV charging stations?

The novel composite crafted by MIT researchers holds the potential to bring about a transformative impact on the electric vehicle (EV) industry. Its unique physical attributes position it as a prospective component of roadways, facilitating inductive charging for electric vehicles.

Yet, it’s important to acknowledge that the complete realization of such advancements necessitates thorough testing and research. Notably, experiments have already been conducted with solar roads serving as EV chargers, as demonstrated in China. However, distinct technologies were employed for those initiatives.
