Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.

Two of humanity’s most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for a novel, low-cost energy storage system, according to a new study...

Nanotechnology offers new approach to increasing storage ability of dielectric capacitors. In the movie ‘Back to the Future,’ Doc Brown and Marty McFly landed in the future in their DeLorean, with time travel made possible by a ‘flux capacitor.’ Today, capacitors are key components of portable electronics to electric cars, providing fast delivery of energy but poor storage capacity. Researchers now report a new approach to increasing storage ability.

In contrast to batteries, which offer high storage capacity but slow delivery of energy, capacitors provide fast delivery but poor storage capacity...
