Ironically, an electric vehicle’s greatest strength is also one of its biggest weaknesses. Rather than internal combustion engines, electric vehicles are powered by rechargeable lithium-ion battery packs. But while EV batteries produce zero emissions, they are quite expensive to manufacture, are not very energy dense, and take quite a while to charge, making EVs much more expensive and leaving most prospective EV drivers filled with range anxiety.
However, a new type of battery technology developed in Australia could allay these fears and completely revolutionize the nascent electric vehicle industry. Graphene Manufacturing Group (“GMG”) based in Brisbane, Australia, has developed aluminum-ion cells that are much more energy dense and have shorter charging times compared to lithium-ion batteries. Developed in association with the Australian Institute for Bioengineering and Nanotechnology at the University of Queensland, these batteries utilize aluminum atoms embedded in tiny perforations in graphene planes.
These graphene-aluminum battery cells are said to hold up to three times the energy of the best aluminum-based cells on the market and to charge up to 60 times faster than lithium-ion cells. Additionally, they are a lot safer because they have zero chance of spontaneous overheating due to having no upper Ampher limit, and thanks to the stable base materials in their formulations, recycling them is much easier. GMG is currently using this groundbreaking battery technology to develop prototype coin cells, and according to tests, these coin cells can last three times longer than lithium-ion cells.
Although GMG isn’t the only company developing graphene aluminum-ion cells, its prototypes are easily the strongest and most reliable with the fastest charging times, says GMG managing director Craig Nicol. These coin cell prototypes charge so fast they are “basically super capacitors,” he says. On top of that, they will deliver an unbelievable amount of energy without the cooling and heating problems lithium-ion batteries usually face. This means graphene aluminum-ion battery packs won’t require heating or cooling circuits, which can add an extra 80kg to a 100kWh battery pack.
Additionally, the production of these batteries does not require nickel, cobalt and copper. Not only will this reduce the environmental effect of manufacturing batteries, but it will also make the battery-making space much more resilient.
Graphene Manufacturing Group will use this battery technology to develop commercial battery prototypes for everything from watches, phones and laptops to battery electric vehicles and grid storage in concert with University of Queensland technology. According to Nicol, the Australian company will begin customer testing for its commercial coin cell prototype in six months while prototypes for mobile phones and laptops will begin testing in eighteen months.
One can only imagine how the pricing of the models made by electric vehicle sector players such as ev Transportation Services Inc. will change once this superior battery technology passes the customer tests its developers are intending to perform and gets widely applied.
