EVs & Batteries: How Much Lithium is Needed to Decarbonise?
Electrification is one of the most important strategies for reducing emissions from energy according to the International Energy Agency (IEA), allowing renewable sources to take over where liquid and gaseous fuels were before.
With EV sales growing and governments phasing out petrol and diesel cars, demand for lithium-ion batteries to power them is growing too.
This rising appetite is putting pressure on global lithium supplies, raising questions about how much lithium will be needed and if enough can be mined, refined and recycled in time.
The EV-driven lithium surge
Lithium is an essential component in lithium-ion batteries that power EVs.
In 2024, global demand for EV batteries exceeded 950GWh, with more than 90% of lithium consumption now linked to battery production according to the IEA.
An average EV battery requires roughly 8 kg of lithium.
“In a world of high geopolitical tensions, critical minerals have emerged as a frontline issue in safeguarding global energy and economic security,” says Dr Fatih Birol, Executive Director of the IEA.
By 2030, The World Economic Forum (WEF) predicts that annual lithium demand could reach 3 million tonnes (measured as lithium carbonate equivalent or LCE), more than triple the 2022 figure of around 650,000 tonnes.
This is directly tied to the anticipated exponential growth of EV sales, as countries phase out internal combustion vehicles and consumers opt for greener alternatives.
A regional breakdown
Lithium demand will be dominated by key automotive markets:
- China is projected to need 1.18 tonnes of LCE annually by 2030
- Europe is expected to require around 718,490 tonnes
- The United States will likely need approximately 627,772 tonnes, according to the IEA.
Supply gaps and market imbalances
Despite significant investment in mining and refining, the lithium supply chain is struggling to scale fast enough.
According to the IEA, the average new mine takes more than 16 years to come online and production is highly concentrated.
Data from WEF shows that Australia leads current output, while the majority of reserves lie in the “Lithium Triangle” of Chile, Argentina and Bolivia — regions facing high water stress and environmental concerns.
More than half of lithium is produced in areas already suffering from water scarcity.
By the end of the decade, a supply-demand mismatch is possible.
Forecasts from the IEA and others warn that shortages could begin as early as 2025.
“Even in a well-supplied market, critical mineral supply chains can be highly vulnerable to supply shocks, be they from extreme weather, a technical failure or trade disruptions,” says Fatih.
“The impact of a supply shock can be far-reaching, bringing higher prices for consumers and reducing industrial competitiveness.”
Innovation and recycling
Solutions are emerging, but slowly:
- Direct lithium extraction (DLE) could improve efficiency and reduce environmental impact, though it remains largely unproven at scale
- Battery recycling may expand after 2030 as early EV batteries reach end-of-life, potentially reducing primary lithium demand
- New chemistries, such as sodium-ion batteries, avoid lithium entirely but lack the energy density required for most current EV applications.
A critical decade ahead
To meet global net zero goals, around two billion EVs must be on the road by 2050, WEF data shows
Yet with global reserves at roughly 22 million tonnes, according to the US Geological Survey, the world has just enough lithium — in theory — to produce that many vehicles.
In practice, economic, political and environmental constraints mean not all reserves can be accessed, processed or used efficiently.
The industry faces a pressing challenge: how to triple lithium production in under a decade, without triggering unsustainable extraction practices or geopolitical bottlenecks.
