A breakthrough graphene aluminum-ion battery technology could blow lithium-ion away for power, ... [+] energy density, recharging speed and environmental friendliness.
Range anxiety, recycling and fast-charging fears could all be consigned to electric-vehicle history with a nanotech-driven Australian battery invention.
The graphene aluminum-ion battery cells from the Brisbane-based Graphene Manufacturing Group (GMG) are claimed to charge up to 60 times faster than the best lithium-ion cells and hold three time the energy of the best aluminum-based cells.
Based on breakthrough technology from the University of Queensland’s (UQ) Australian Institute for Bioengineering and Nanotechnology, the battery cells use nanotechnology to insert aluminum atoms inside tiny perforations in graphene planes.
Aluminum-ion technology has intrinsic advantages and disadvantages over the preeminent lithium-ion battery technology being used in almost every EV today.
The coin battery will be the first Graphene Manufucturing Group aluminium-ion battery in production, ... [+] starting early next year.
Another advantage is that the GMG graphene aluminum-ion cells do not use copper, which costs around US$8470 a tonne. »
