Concrete is the world's most consumed material after water. Because it already surrounds us in the built environment, researchers have been exploring the idea of using concrete to store electricity—turning buildings into giant batteries. The idea has been gaining ground as we have come to increasingly rely on renewable energy from the wind and sun: rechargeable batteries are necessary when the breeze dies down or darkness falls.

Experimental concrete batteries have only managed to hold a small part of what a traditional battery does. But one team now reports in Buildings that it has developed a rechargeable original model that could represent a more than 900 percent increase in stored charge, compared with earlier attempts.

A live-in concrete battery might sound unlikely. Still, "you can make a battery out of a potato," notes Aimee Byrne. In a future where sustainability is key, she likes the idea of buildings that avoid waste by providing shelter and powering electronics.

Although the new design stores more than 10 times as much power as earlier attempts, it still has a long way to go: 200 square meters of it "can provide about 8 percent of the daily electricity consumption" of a typical U.S. home, Zhang says.

This is not enough to compete with today's rechargeable devices. "We're getting milliamps (毫安) out of concrete batteries—we're not getting amps (安培), "Byrne says." We're getting hours as opposed to days of charge." But she adds that" concrete batteries are completely in their childhood, compared to other battery designs." The earliest batteries were simple andbulky. Researchers experimented with new materials and designs
