Coming from Australia’s CSIRO, “The UltraBattery is a hybrid energy storage device that integrates a supercapacitor with a lead acid battery in one unit cell.” Translation: a battery which is cheaper, lasts longer, and provides more power. The battery is aimed at use in hybrid electric vehicles (HEVs).
So exactly how much better is this thing, you ask? Here are the tech specs:
4x longer cycle life
50 percent more power than lead acid counterparts
about 70 percent less expensive than current HEV battery systems
faster charge and discharge rates
The battery has performed well in recent testing in an HEV which surpassed 100,000 miles. Hopefully these are released commercially soon. The world could use some more plug-in hybrids, and these batteries are sure to make plug-ins sell.
