The global push towards renewable energy and electric vehicles has sharply escalated demand for lithium, an essential mineral for battery production. This surge has exposed significant vulnerabilities in the lithium supply chain, particularly due to the heavy concentration of processing capacity in China. Despite producing only around 13% of the world's raw lithium, China controls roughly 60% of global lithium refining capacity. This imbalance has driven governments worldwide to bolster their strategic efforts for lithium supply chain security, recognising the risks posed by geopolitical tensions and reliance on a single dominant player.
A major bottleneck exists as traditional lithium-producing regions like Australia mainly extract raw materials but lack the downstream processing infrastructure. Consequently, raw lithium concentrates often must be exported to China for conversion into battery-grade chemicals before being shipped back to manufacturing centres overseas. This dependency increases exposure to supply disruptions and trade restrictions, raising alarm as the global electrification movement continues to accelerate. Projections indicate lithium demand could soar by up to 400% by 2030, highlighting the urgent need for diversified, resilient supply chains.
Governments have increasingly deployed a range of financial incentives and direct investments to develop domestic lithium capacity. In the United States, the Bipartisan Infrastructure Law has earmarked over $3 billion for critical mineral projects, including extraction, processing, and recycling, with the aim of catalysing around $16 billion in combined public-private investment. These measures include conditional loan commitments, tax credits, research grants, infrastructure funding, and risk-sharing to attract and secure capital for projects that require hundreds of millions or even billions in upfront investment and long lead times.
For example, the U.S. Department of Energy (DOE) has spearheaded major loan guarantee programmes to mitigate financing risks for lithium projects, such as the Thacker Pass lithium mine in Nevada. The government recently took an unprecedented step by acquiring a 5% equity stake in Lithium Americas, the company developing Thacker Pass, accompanied by a $435 million federal loan and deferred loan payments. This project alone has the potential to supply lithium for over 800,000 electric vehicles annually, a critical capacity expansion aligned with America's strategy to reduce dependence on Chinese imports. In August 2025, the U.S. administration also proposed nearly $1 billion in new funding focused on domestic critical mineral development, including battery manufacturing and recycling technologies, further signalling an aggressive pivot towards supply chain independence.
Canada is likewise harnessing its lithium brine resources with policies supporting innovative extraction innovations and expedited regulatory approvals. Projects such as E3 Lithium’s Clearwater facility in Alberta are leveraging proximity to existing oil and gas infrastructure to establish cost-efficient lithium carbonate production, aiming to serve North American battery manufacturers while adding value domestically.
In Europe, the launch of the Critical Raw Materials Act has marked a significant policy shift, backed by the European Investment Bank's recent funding support for lithium projects. The continent is advancing capacity expansions including Portugal’s Barroso spodumene project and emphasises stringent environmental compliance to ensure sustainable development. Despite these efforts, Europe faces substantial battery supply deficits, with studies projecting a lithium-ion battery shortfall of around 70 GWh in 2025, underscoring the need for further upstream investment in raw materials and processing.
Aligned international partnerships are also proving crucial. The Minerals Security Partnership, led by the U.S. Department of State, brings together allied nations to coordinate supply chain development, share technical expertise, pool investment strategies, and mitigate geopolitical risks through diversification. Trade agreements increasingly embed provisions on critical minerals, facilitating technology transfer and long-term supply relationships, which are vital to secure stable lithium access.
Nevertheless, the lithium market remains volatile and complex. Spot prices have oscillated significantly since their peak in late 2022, driven by supply-demand imbalances and speculative trading. The recent suspension of operations at several Chinese lithium mines, including a major facility operated by battery giant CATL in Yichun due to an expired license, caused an immediate surge in lithium prices and stock gains for lithium producers internationally. This production halt, reportedly part of a broader Chinese government crackdown on overcapacity, has heightened concerns about future supply tightening. China’s dominant refining position, controlling around 60% of global capacity, and its integrated mining and battery production infrastructure accentuate the global repercussions of such domestic production pauses.
These events highlight the vulnerabilities of a geographically concentrated supply chain amid shifting industrial policies. Market participants and policymakers alike acknowledge that robust government support is vital to accelerate the scaling of domestically integrated lithium supply chains. Yet, such interventions need to balance market dynamics carefully to avoid inefficiencies; instead, transparent price mechanisms and technological innovation must underpin long-term supply stability.
Crucially, environmental and social considerations are now integral to lithium sector development. Governments increasingly demand adherence to sustainable extraction practices, water conservation, waste management, indigenous rights consultations, and biodiversity safeguards. Advanced technologies, such as Direct Lithium Extraction (DLE), which reduces water usage and environmental footprint compared to traditional evaporative methods, are receiving targeted government backing to facilitate responsible growth in new lithium projects.
Beyond traditional producers, emerging markets in South America and Africa are stepping up efforts to participate more fully in the lithium value chain. Countries like Chile and Argentina are enforcing local processing mandates and fostering technology transfer partnerships, while African nations, including Zimbabwe and Namibia, are boosting geological surveys, capacity building, and infrastructure improvements to attract investment and secure domestic benefits.
Despite these positive movements, substantial challenges remain in regulatory coordination and policy stability. Multiple government agencies must streamline permitting processes and harmonise standards to avoid costly delays. Additionally, balancing national industry protection with international cooperation and open markets requires careful policy calibration to prevent trade conflicts while securing critical mineral supplies.
Looking ahead, government strategies for lithium supply security will likely evolve to emphasise recycling, circular economy approaches, next-generation battery technologies, and the integration of artificial intelligence and automation in mining and processing. Long-term strategic planning that synchronises infrastructure, workforce development, and innovation with industry cycles will be critical for maintaining competitive, secure supply chains over decades.
Ultimately, the transformation of lithium supply chains represents a fundamental shift in how nations prioritise resource security amid the clean energy transition. Success will depend on navigating complex market and geopolitical factors while upholding environmental and social responsibility, ensuring resilient and diversified supply networks essential for the global energy future.
