Developed under collaborative efforts from ITRI and Stanford University, the first commercially viable aluminum battery is born. The battery uses an aluminum anode, a graphite-structured carbon cathode and a highly safe ionic liquid electrolyte. It is capable of ramping between 100 percent and 20 percent full capacity in two-minutes repeatedly for more than 10,000 cycles, while maintaining an exceptional coulombic efficiency (CE) of 98 percent throughout this cycle life. URABat, an ultrafast rechargeable aluminum battery uses simple aluminum as its anode, structured graphitic carbon as its cathode, and filled with ionic liquid electrolytes in between, has successfully broken the barriers of low discharge voltages (less than 0.55 V) and insufficient life cycle (less than 100 cycles) which hampered the development of aluminum batteries for decades.
