Carbon fiber energy storage concrete

Can a carbon-cement supercapacitor store energy?

MIT engineers created a carbon-cement supercapacitor that can store large amounts of energy. Made of just cement, water, and carbon black, the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.

Can concrete be used for energy storage?

We've written before about the idea of using concrete for energy storage – back in 2021, a team from the Chalmers University of Technology showed how useful amounts of electrical energy could be stored in concrete poured around carbon fiber mesh electrodes, with mixed-in carbon fibers to add conductivity.

Can carbon laced concrete be used as a heating system?

Besides its ability to store energy in the form of supercapacitors, the same kind of concrete mixture can be used as a heating system, by simply applying electricity to the carbon-laced concrete. Ulm sees this as “a new way of looking toward the future of concrete as part of the energy transition.”

Can energy-harvesting concrete be used for smart infrastructures?

Therefore, the use of energy-harvesting concretes can turn infrastructures into distributed energy storages or generators, thus supporting the next generation of smart infrastructures, such as electrical chargers, sensors, illuminations and communications.

Can carbon fiber recharge power?

In this case, conductive carbon fibers mixed into cement (a main ingredient of concrete) substitute for the electrolyte. The researchers embedded layers of a carbon-fiber mesh, coated in nickel or iron, to act as the plates. This setup proved capable of discharging power and then recharging.
