New Breakthrough in Energy Storage – MIT Engineers Create Supercapacitor out of Ancient Materials::Constructed from cement, carbon black, and water, the device holds the potential to offer affordable and scalable energy storage for renewable energy sources. Two of humanity’s most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for
Why can’t the steel rebar just be part of the conductive carbon anode?
The design already assumes the concrete is riddled with conductive material. Why would adding fat wires hurt?
