MIT Develops New Model to Speed Lithium Battery Charging

Concrete “battery” developed at MIT now packs 10 times the power

New concrete and carbon black supercapacitors with optimized electrolytes have 10 times the energy storage of previous designs and can be incorporated into a wide range of architectural forms.

Scientists Are Turning Giants Slabs of Concrete Into Freaking Batteries

The world is built with concrete. Could it one day be powered by it?

Breakthrough paves the way for faster-charging batteries

MIT maps lithium’s hidden speed limits to unlock next-gen EV batteries

The performance of lithium-ion batteries is dictated by the speed at which lithium ions "intercalate," or insert themselves, into a solid electrode.

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…
