Green battery gives non-stop energy for years

Scientists at the Technion-Israel Institute of Technology have developed a new, environmentally friendly silicon-air battery capable of supplying non-stop power for thousands of hours without needing to be replaced.

Created from oxygen and silicon, such batteries would be lightweight, have an unlimited shelf life, and have a high tolerance for both humid and extremely dry conditions.

Potential uses include medical applications (example, powering diabetic pumps), sensors and microelectronics structured from silicon. “Silicon-air batteries will be used like the ones already in use today,” said lead researcher Yair Ein-Eli. “But by using silicon – a safe, non-toxic, stable and more common material – we can create batteries with infinite shelf life and high energy capacity,” he added.

Silicon-air batteries would be able to provide savings in cost, weight as they lack the built-in cathode used in conventional batteries.
