According to research conducted by Graphene Manufacturing Group (GMG), a technology company based in Australia, Graphene aluminium-ion EV batteries can charge 60 times faster than lithium-ion batteries which are considered the best electric mobility solution.
Until now EV manufacturers believed that a lithium-ion battery is the most efficient power source to run electric vehicles. However, this concept has been debunked by GMG and their immense research.
In addition to the faster charging ability of Graphene aluminium-ion EV batteries, the company claims that this new technology can hold three times more energy, is much safer and durable and has a lesser impact on the environment when compared to traditional batteries.
It is believed that GMG will be producing and marketing coin cells made out of Graphene aluminium-ion by the end of 2021 or early 2022. The company also have plans to release automotive pouch cells by early 2024.
The company is known for developing energy storage products by using its own unique manufacturing process- GMG produces graphene from methane and not mined graphite as they believe that it can help them produce high-quality products that can be tweaked according to their interest. GMG claims that this material can be used in different kinds of products starting from phones, laptops all the way up to electric vehicles and storage battery systems.

The University of Queensland has announced a research agreement which stated that GMG and the University of Queensland will be developing the aluminium-ion cells in the month of April. The initial data of the experiments have been released by the Australian Institute for Bioengineering and Nanotechnology.
GMG CEO and Managing Director Craig Nicol said, "We are currently looking to bring coin cell commercial prototypes for customer testing in 6 months and a pouch pack commercial prototype used in mobile phones, laptops etc. for customer testing in 18 months. We are really excited about bringing this to market. We aim to have a viable graphene and coin cell battery production facility project after customer validation that we would likely build here in Australia," said Craig Nicol.
Research and Testing are continuing in the field, however, a license agreement has already been signed between GMG and the University of Queensland commercialisation company. Customer testing is expected to begin in the fourth quarter of 2021.
Dr Ashok Nanjundan, GMGs Chief Scientific Officer, said, "This is a real game-changing technology which can offer a real alternative with interchangeable battery technology for the existing lithium-ion batteries in almost every application with GMGs Graphene and UQs patent-pending aluminium ion battery technology. The current nominal voltage of our batteries is 1.7 volts, and work is being carried out to increase the voltage to directly replace existing batteries and which lead to higher energy densities."

"The real differentiator about these batteries is their high power density of up to 7000 watts/kg, which endows them with a very high charge rate. Furthermore, graphene aluminium-ion batteries provide major benefits in terms of longer battery life (over 2000 charge/discharge cycles testing so far with no deterioration in performance), battery safety (very low fire potential) and lower environmental impact (more recyclable)," said Dr Ashok Nanjundan.
