About Graphene Manufacturing Group Ltd.

Graphene Manufacturing Group is an Australian-based clean technology company that develops, makes and sells energy saving and energy storage solutions, enabled by graphene manufactured via in-house production process. Graphene Manufacturing Group uses its own proprietary production process to decompose natural gas (methane) into its natural elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high-quality, low-cost, scalable, tuneable, and low- or no-contaminant graphene suitable for use in clean technology and other applications.

The company's present focus is to derisk and develop commercial scale-up capabilities and secure market applications. In the energy savings segment, Graphene Manufacturing Group has initially focused on graphene enhanced heating, ventilation and air conditioning (HVAC-R) coating (or energy-saving coating), which is now being marketed into other applications, including electronic heat sinks, industrial process plants and data centres. Another product Graphene Manufacturing has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines.

In the energy storage segment, Graphene Manufacturing Group is working with financial support from the Australian Government to progress R&D (research and development) and commercialization of graphene ion batteries. Graphene Manufacturing Group has also developed a graphene additive slurry that is aimed at improving the performance of lithium-ion batteries.

Graphene Manufacturing Group's four critical business objectives are:

• Produce graphene and improve/scale cell production processes;
• Build revenue from energy-saving products;
• Develop next-generation battery;
• Develop supply chain, partners and project execution capability.
