Rechargeable Aluminium-ion Battery could replace Lithium-ion and Alkaline batteries

Rechargeable Aluminium-ion Battery could replace Lithium-ion and Alkaline batteries

Stanford University Professor Hongjie Dai and colleagues have developed a high-performance aluminum battery. While it has been well known for some time now that rechargeable aluminum-based batteries could offer the possibility of low cost, low flammability and high capacity, research efforts have encountered numerous problems, such as cathode material disintegration, low cell discharge voltage and inadequate life cycles with rapid capacity decay. A key challenge has been in finding a cathode material that would result in the battery generating sufficient voltage after repeated cycles of charging and discharging. Recently, Stanford University scientists have developed the first high-performance aluminum battery that's fast-charging, long-lasting and inexpensive. "We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline ba...
