Cement capacitor energy storage

What can the carbon-cement supercapacitor store?

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 cement be used for energy storage in supercapacitors?

In recent years, cement has undergone a transition within the realm of battery energy storage, evolving from its original function as an electrode additive to an electrolyte enhancer, and subsequently, it has been increasingly employed for energy storage in supercapacitors.

Could a supercapacitor provide cheap and scalable energy storage?

MIT engineers have created a “supercapacitor” made of ancient, abundant materials, that could provide cheap and scalable energy storage for renewable energy sources. The device is made of cement, carbon black, and water.

Are carbon–cement supercapacitors a scalable bulk energy storage solution?

Carbon–cement supercapacitors as a scalable bulk energy storage solution. Proceedings of the National Academy of Sciences, 2023; 120 (32) DOI: 10.1073/pnas.2304318120 Massachusetts Institute of Technology. "Energy-storing supercapacitor from cement, water, black carbon."

Can a carbon-cement device 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.

What makes concrete a supercapacitor?

Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength. Cement and water, with a small amount of carbon black mixed in, self-assembles into fractal branches of conductive electrodes, turning concrete into an energy-storing supercapacitor.
