Rechargeable Aluminum Battery Developed

URABat is an ultrafast, commercially viable rechargeable aluminum battery, developed in collaboration between ITRI, Taiwan's Industrial Technology Research Institute, and Stanford University.

Facts about URABat:

  • URABat is fast: It can be fully charged in just one minute for more than 10,000 cycles, while maintaining an exceptional coulombic efficiency (CE) of 98 percent throughout its life.
  • URABat is safe, because all components in the battery system, including the aluminum and graphite electrodes and the isolating membrane, are inert.
  • URABat is ideal for renewable energy storage and electric vehicles: it will compete with the traditional lead acid battery when applied in large energy storage devices, lightweight electric scooters, and motorized bicycles.
  • Lastly, it is environmentally friendly and financially advantageous, as aluminum constitutes an incredible 8.2% of the Earth's crust.
