Could a supercapacitor provide cheap and scalable energy storage?

Made of cement, carbon black, and water, the device could provide cheap and scalable energy storage for renewable energy sources. MIT engineers have created a “supercapacitor” made of ancient, abundant materials, that can store large amounts of energy.

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.

Batteries and capacitors do a similar job—storing electricity—but in completely different ways.

Are energy storage devices unipolar?

Furthermore, because energy storage devices are unipolar devices, for practical application, we must consider the non-switching I–V transients, as there will be no voltage of the opposite polarity to switch any ferroelectric polarization that may be present.

How much energy can a supercapacitor pack into a battery?

The biggest commercial supercapacitors made by companies such as Maxwell Technologies® have capacitances rated up to several thousand farads. That still represents only a fraction (maybe 10–20 percent) of the electrical energy you can pack into a battery.
