GMG's Graphene Aluminium-Ion Battery: Collaboration with World Leading USA Battery Innovation Centre and Next Steps Toward Commercialisation

Brisbane, Queensland, Australia--(ACN Newswire - March 3, 2025) - Graphene Manufacturing Group Ltd. (TSXV: GMG) (OTCQX: GMGMF) ("GMG" or the "Company") is pleased to provide the latest progress update on the Graphene Aluminium-Ion Battery technology ("G+AI Battery") being developed by GMG and the University of Queensland ("UQ") under a Joint Development Agreement with Rio Tinto, one of the world's largest metals and mining groups.

Notably, this update includes information about GMG's G+AI Battery regarding:

• Scaling with the Battery Innovation Center of Indiana, United States.
• Electrochemistry Optimisation
• 1000 mAh Battery Cell Capacity Reached (Previously)
• Battery Technology Readiness Level
• Next Steps Toward Commercialisation and Market Applications
• Next Generation Battery Performance
• Important Milestones for GMG's Graphene Aluminium-Ion Battery Development

Scaling with the Battery Innovation Center of Indiana, United States.

GMG is pleased to announce that it has signed a service contract with the Battery Innovation Center of Indiana ("BIC") in the United States of America to support the next phase of development of the Graphene Aluminium-Ion Battery.

BIC is a collaborative initiative designed to incorporate leadership from renowned universities, government agencies, and commercial enterprises. BIC is a public-private partnership and a not-for-profit organization focusing on the rapid development, testing and commercialization of safe, reliable and lightweight energy storage systems for defense and commercial customers. BIC is a unique organization that has been leading battery cell development for world leading battery companies for over 10 years and has carried out over 500 battery development projects.

BIC's mission is to accelerate innovation in the field of battery technology by providing access to the entire spectrum of R&D to commercialization, including low volume production, in a single 40,000 square foot facility, located in Newberry, an hour south of Bloomington, Indiana. Under one roof and with virtual connections to the research and manufacturing facilities of its partners, BIC has capabilities in all aspects of the battery life cycle.

By collaborating with BIC, GMG can take advantage of BIC's technological capabilities and manufacturing facilities and avoid the capital cost of building a pilot plant, that can cost more than AU$10 million dollars, to produce sample cells in advance of mass production. Under its service agreement with BIC, GMG will pay for services rendered and retain all intellectual property of the development work. The service agreement with BIC will enable GMG to optimize BIC's cell design and battery manufacturing equipment during its scale up of battery production, thereby delaying capital expenditures for manufacturing capacity until battery development is further derisked.

GMG is very pleased to work with BIC on this next phase in the development of GMG's next generation battery.

Electrochemistry Optimisation

The Company is currently optimising the G+AI Battery pouch cell electrochemistry - which is a standard battery development process step (please see Battery Technology Readiness Level section below).

The Company has developed significant knowledge regarding the electrochemistry of the pouch cells since achieving the targeted 1 Ah cell capacity in February 2024.

The challenges faced by the G+AI Battery during this phase of its maturation are very similar to other battery chemistries that have been developed into mass production - including Lithium-Ion batteries.

The performance of the pouch cells will be communicated upon successfully producing a repeatable and 3rd party tested 1000 mAh+ battery pouch cell.
