Global demand for lithium, a critical mineral at the heart of electric vehicle batteries and energy storage systems, is projected to surge by 353% by 2040, according to the United Nations Conference on Trade and Development (UNCTAD). The forecast underscores the accelerating strain on mineral supply chains as governments and corporations race to decarbonise transport and power systems.
Lithium has become indispensable to the global energy transition. It is a key component in lithium-ion batteries, which power electric vehicles (EVs), grid-scale storage systems, and a growing range of consumer electronics. UNCTAD’s projection signals that demand growth is not only robust but structurally entrenched, driven by long-term shifts in industrial policy and consumer adoption.
The anticipated surge raises concerns about a widening supply gap. Mining projects typically require years of development, while refining capacity remains concentrated in a small number of countries. This imbalance increases the risk of bottlenecks, price volatility, and strategic competition over resource access.
Analysts say the implications extend beyond commodities markets. A sustained lithium shortfall could slow EV adoption timelines, raise battery costs, and complicate national climate targets. Governments in Europe, North America, and Asia have already begun classifying lithium and related minerals as strategic resources, accelerating efforts to secure domestic production and diversify import sources.
UNCTAD’s outlook also highlights structural vulnerabilities in the global supply chain. Extraction is geographically concentrated, while processing capacity is even more tightly controlled, creating dependency risks for manufacturers. This has prompted renewed investment in alternative battery chemistries, recycling technologies, and substitution research, though none are expected to fully displace lithium in the near term.
For investors, the forecast reinforces the long-term bullish narrative around critical minerals, even as short-term price cycles remain volatile. Mining firms, battery manufacturers, and downstream EV producers are expected to face both opportunity and constraint as demand scales sharply over the next decade and a half.
At the same time, environmental and social pressures are intensifying scrutiny of new mining projects. Water usage, land disruption, and community impact assessments are increasingly shaping project approvals, particularly in Latin America and Australia, two of the largest lithium-producing regions.
UNCTAD’s projection ultimately reflects a broader reality: the energy transition is materially resource-intensive. While technological innovation continues to improve efficiency, the scale of electrification suggests that competition for lithium will remain a defining feature of global industrial strategy through 2040.
