New in Popular Mechanics: “Scientists have developed concrete with self-healing abilities, concrete that acts as a kind of carbon sink, and concrete that can even increase crop yields. Now scientists from the Massachusetts Institute of Technology (MIT) have improved upon a radical new innovation—battery concrete. A new study published in the journal PNAS details how a mixture of cement, water, ultra-fine carbon black (filled with nanoscale particles), and electrolytes can form what they call an ‘electron-conducting carbon concrete,’ or ec³, which creates a conductive nanonetwork that can act like a battery.” Read the article: https://www.popularmechanics.com/science/green-tech/a68296029/slabs-of-concrete-batteries/
Scientists are turning giants slabs of concrete into freaking batteries
