Pourable Batteries Could Store Green Power

The race is on to develop smaller, more powerful and more solid batteries for devices like laptop computers, cell phones, GPS receivers and other portable devices.

Scientists at MIT are taking the opposite approach, developing large, eco-friendly stationary batteries made entirely from liquid metal that would store large amounts of power from wind farms or solar cells or serve as backup power sources for hospitals.

"Since these batteries won't be in someone's hand or in a car, we don't have to make them crash-worthy, idiot-proof, and it doesn't have to operate at around body temperature," said Don Sadoway, a scientist at the Massachusetts Institute of Technology who, along with graduate student David Bradwell and fellow professor Gerbrand Ceder, is developing the molten metal battery.
