The UltraBattery is a hybrid energy storage device that integrates a supercapacitor with a lead acid battery in one unit cell
Ms Rosalie Louey sits at a laboratory desk wearing her safety goggles and lab coat and uses a variety of instruments to prepare components for the UltraBattery.
UltraBattery applications include implementation in hybrid electric vehicles and smoothing the intermittency of wind-generated power.

The UltraBattery offers a number of advantages over conventional car batteries:

cycle life is four times longer
50 per cent more power than lead acid batteries counterparts
approximately 70 per cent less expensive than current HEV battery systems
faster charge and discharge rates.

Field tests for the wind energy storage application are being conducted at the CSIRO Energy Centre in Newcastle, New South Wales, Australia.

A similar application is expected to be developed for solar energy production.

CSIRO has signed an UltraBattery commercialisation and distribution agreement with Japan's Furukawa Battery Company and United States manufacturer, East Penn.
