Australia is transitioning from a predominantly upstream supplier of critical minerals toward a strategic partner in circular, low-carbon battery value chains. At the same time, the European Union (EU) is embedding sustainability, circularity and traceability into conditions for battery market access. This creates a strong alignment between Australia’s industrial upgrading agenda and Europe’s regulatory-driven demand for circular battery systems.
Reflecting on these strengthening linkages, IP Australia has collaborated with the European Patent Office (EPO) on a new EPO Technology Insights report on battery circularity and critical metals refinement technology. The report, published jointly with the International Atomic Energy Agency, includes the following case study on Australia’s evolving value chain position and patent activity.
Australia’s value chain position
Australia is a foundational supplier of battery inputs. It is the world’s largest producer of lithium and a major global producer of nickel, manganese, cobalt, copper and graphite used in battery cathodes and anodes.1 Historically, these materials have largely been exported as concentrates, capturing limited downstream value.
Current national strategies aim to shift Australia up the value chain into minerals refining, battery materials, recycling and other circularity technologies. The Critical Minerals Strategy (2023–2030), National Battery Strategy (2024) and Circular Economy Framework (2024) collectively emphasise processing capability, sustainability and value capture. Investments in research, skills and advanced manufacturing are strengthening Australia’s capacity in battery recycling and materials recovery, positioning it as a potential provider of circular economy technologies and materials for European markets.
EU regulatory demand and the strategic fit with Australia
EU policy frameworks are reshaping global battery value chains by integrating lifecycle sustainability into market access. The EU Battery Regulation and the Critical Raw Materials Act contain traceability and sustainability provisions that support recycling and reuse.
For Australian firms, this translates into:
- more stable demand for responsibly sourced minerals and refined chemicals,
- commercial incentives to develop recycling and resource recovery technologies, and
- a clear rationale for protecting relevant IP in European markets.
This strategic alignment has been formalised through cooperation instruments. In May 2024, Australia and the EU signed a Memorandum of Understanding on a Strategic Partnership on Sustainable Critical and Strategic Minerals, covering exploration, processing, refining, recycling and related standards. The partnership reflects a shared view that supply chain security and circular economy objectives are mutually reinforcing.
Emerging Australia-EU industrial linkages
Policy alignment is increasingly translating into concrete industrial, financial and IP linkages across battery value chains.
Financing and offtake arrangements are expanding, including deeper cooperation between the European Investment Bank and Australia to support critical minerals and battery projects. European automotive and energy firms are securing Australian battery inputs through equity investments and long‑term offtake agreements.
Australian firms are also embedding directly into European value chains. For example, Talga Group is developing an integrated graphite mine and anode refinery in Sweden, designated a Strategic Project under the EU Critical Raw Materials Act. In recycling, Primobius – a joint venture between Australia’s Neometals and Germany’s SMS Group – has deployed patented lithium‑ion battery recycling technology in Europe, including supplying IP for Mercedes‑Benz’s battery recycling plant in Germany.
Together, these examples illustrate complementary specialisation: Australia contributes critical minerals, mid‑stream processing capability and circularity‑focused IP, while Europe provides capital, scale and regulatory‑driven demand.
Innovation, patents and EU linkages
EPO analysis shows that Australian applicants account for a small share of global patent filings in battery circularity and critical metal refinement technologies. These results are consistent with IP Australia research.2 Australian-origin patent filings in these areas have a clear technical focus on the refinement and treatment of critical metals for batteries.
Australian applicants account for an average 10 international patent families per year in these areas of technology. In the refinement of critical metals for batteries, Australian applicants account for 8.9% of patent families published since 2000.
More recently, Australian applicants have become more engaged in battery circularity, with a marked increase in applications for materials recovery technologies. These technologies were the focus of less than a quarter of international patent families produced by Australian applicants between 2014 and 2021 in relation to battery circularity. The remaining three-quarters focused on critical mineral refinement. After 2021, the picture has reversed: material recovery is the focus of more than half of patent families originating from Australia related to battery circularity in recent years.
Australian battery innovators frequently seek patent protection in Europe alongside other major jurisdictions with manufacturing ecosystems and regulatory demand. Australia’s assignee profile is dominated by public research organisations and SMEs rather than large manufacturers, suggesting patents function primarily as:
- enablers of collaboration and licensing,
- signals to investors and strategic partners, and
- intellectual infrastructure linking upstream resources to downstream manufacturing and recycling.
This aligns with an innovation model centred on process IP, services and partnerships rather than vertically integrated cell production.
Summary
Australia is evolving from a raw materials exporter into a partner for Europe on battery circularity technologies. EU regulation, Australian industrial policy and emerging innovation capability are jointly shaping new value chain linkages. The opportunity is a mutually reinforcing partnership: Australia contributes strengths in critical minerals, processing and circular innovation, while Europe pairs industrial scale and capital with strong innovation ecosystems and regulatory frameworks that drive sustainable demand.
