The Australia-based clean-tech company listed that produces graphene and hydrogen by cracking methane instead of mining graphite has shared the initial performance data when tested in coin cells for the patent-pending surface perforation of graphene in aluminium-ion batteries developed by the Company in association with the University of Queensland.
The experiments were carried out at the Australian Institute for Bioengineering and Nanotechnology (“AIBN”), University of Queensland. Presently, GMG Graphene is being used to produce coin cell prototypes for customer testing in Q4 2021. The initial performance data is presented below:
A few days earlier, GMG announced the execution of a research agreement with the University of Queensland’s Australian Institute for Bioengineering and Nanotechnology to develop graphene aluminium-ion batteries.
As per the agreement, GMG will manufacture commercial battery prototypes for watches, phones, laptops, electric vehicles and grid storage with technology developed at the University of Queensland.
GMG has also inked a license agreement with Uniquest, the University of Queensland commercialization company, which delivers GMG an exclusive license of the technology for battery cathodes.
Craig Nicol, CEO and Managing Director, GMG 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 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.”
Dr. Ashok Nanjundan, GMG’s 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 GMG’s Graphene and UQ’s 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 very 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),” added Dr. Ashok.
As the research and development of the graphene aluminium batteries progress, GMG will come up with further disclosures regarding the performance and development.
