Concrete 'battery' now packs 10 times the power

Concrete 'battery' now packs 10 times the power

Concrete already builds our world, and now it's one step closer to powering it, too. Made by combining cement, water, ultra-fine carbon black (with nanoscale particles), and electrolytes, electron-conducting carbon concrete (ec3, pronounced "e-c-cubed") creates a conductive "nanonetwork" inside concrete that could enable everyday structures like walls, sidewalks, and bridges to store and release electrical energy. In other words, the concrete ar…
