The UltraBattery is a remarkable CSIRO invention that has turned the conventional lead-acid battery – a 150 year-old energy-storage system – into a dynamic technology.

The unique design combines two everyday energy-storage devices: the lead-acid battery (battery found in cars) and a supercapacitor (device that powers camera flashes). The result is an economical, super fast-charging battery with long-life power.

The UltraBattery is about 70 per cent cheaper to make than batteries with comparable performance and can be made using existing manufacturing facilities.

With a wealth of applications possible, the UltraBattery is ideally suited for hybrid-electric and conventional vehicles, renewable energy storage, remote area power supply, emergency power backup and forklift trucks.
