Australian company Graphene Manufacturing Group has developed graphene aluminium-ion battery cells that surpass the performance of others currently on the market while being easier to recycle.
The innovative battery cells ‘charge up to 60 times faster than the best lithium-ion cells and hold three time the energy of the best aluminium-based cells’. The Brisbane-based business says they are also safer, with no upper Ampere limit to cause spontaneous overheating.
Best of all, recycling the cells is not a problem at all, thanks to their stable base materials. Testing also shows the coin-cell validation batteries also last three times longer than lithium-ion versions.
GMG plans to go into production in early 2022. ‘We are currently looking to bring coin cell commercial prototypes for customer testing in six months and a pouch pack commercial prototype – used in mobile phones, laptops etc. – for customer testing in 18 months,’ Company ceo Craig Nicol comments.
The recycling-friendly cells are based on a ‘breakthrough’ nanotechnology developed by the University of Queensland’s (UQ) Australian Institute for Bioengineering and Nanotechnology. Its researchers used the method to insert aluminium atoms inside tiny perforations in graphene planes.
