A new partnership linking Australian graphite resources with Japanese battery anode manufacturing is set to establish one of the region’s first fully integrated graphite-to-anode supply chains, strengthening both nations’ roles in the fast-growing electric vehicle and energy-storage sectors.

The collaboration brings together Idemitsu Australia, Idemitsu Kosan, Marubeni, NSC, and Graphinex.

Under the agreement, Graphinex, supported by Idemitsu, will advance development of its natural graphite projects in Queensland, connecting with Marubeni and NSC’s plans to establish a new downstream anode manufacturing facility in Japan.

The partnership aims to supply cost-competitive, high-purity graphite anode material directly to Japan’s expanding battery market.

Japan, a major producer of lithium-ion batteries, remains heavily reliant on imported anode materials.

With graphite accounting for over 90 per cent of today’s battery anodes, securing stable and diversified supply routes has become a priority for manufacturers and governments worldwide.

Idemitsu Australia CEO Steve Kovac said the collaboration would help bolster supply security at a pivotal moment for the industry.

“The global battery sector needs new, dependable supply routes, and this partnership delivers exactly that,” he said.

“By linking Queensland’s graphite resources with advanced anode manufacturing in Japan, we’re supporting industry growth, reinforcing regional supply chains, and advancing the clean-energy priorities of both countries.”

Graphinex Managing Director Art Malone said the partnership could unlock new economic and industrial opportunities for Queensland.

“Graphinex has the most promising natural graphite resource in the country, and this partnership gives us the opportunity to turn that into real economic value for the region,” he said.

“Working with Idemitsu, Marubeni and NSC brings the investment and capability needed to build a long-term industry around a local resource, creating jobs, developing new skills and strengthening Australia’s role in the critical minerals supply chain.”

The integrated model marks the first time that mining, refining, and anode manufacturing will be linked directly between Australia and Japan.

By connecting resource extraction to end-product manufacturing, the partnership aims to improve supply chain resilience, reduce dependence on single-market suppliers, and diversify sourcing options for critical battery inputs.

For Queensland, the development represents another important step in building the state’s critical minerals industry, with potential benefits including regional development, downstream processing, and job creation in emerging clean technologies.

For Japan, the collaboration ensures a consistent and scalable source of high-quality material essential to electric vehicle and stationary energy storage production.

Establishing new refining and manufacturing capacity in Japan positions the partnership to supply battery producers directly, enhancing supply reliability while supporting both nations’ shared ambitions to strengthen critical mineral supply chains and accelerate the shift toward a low-carbon economy.
