# Where Does the Lithium in EV Batteries Come From? By EV Charge Cables ยท Published 18 October 2026 **The short version** EV battery lithium is mined mainly in Chile, Australia, and Argentina, then refined predominantly in China before being made into cells and battery packs. - Two main extraction methods: brine evaporation in South America and hard rock mining in Australia - Refining is heavily concentrated in China, creating supply chain risk - Recycling and sodium-ion alternatives are reducing long-term dependence on primary lithium mining The lithium in EV batteries is mined from brine deposits and hard rock ore in a relatively small number of countries, with Chile, Australia, and Argentina being among the largest producers. From there it is refined, processed into battery-grade chemicals, and incorporated into cells that are assembled, often in Asia, before being integrated into battery packs fitted to cars. The supply chain is long, concentrated, and a genuine environmental and geopolitical concern, which is why the battery industry is actively working on recycling, alternative chemistries, and diversifying sources. If you are curious about the wider environmental footprint of your [electric car](https://www.evchargecable.co.uk/ev-charging-cable), the lithium question is worth understanding honestly. | Stage | Where it typically happens | Key concern | | --- | --- | --- | | Mining | Chile, Australia, Argentina, China, Zimbabwe | Water use (brine), land disturbance (hard rock), local community impact | | Refining | Predominantly China | Geographic concentration; energy intensity of processing | | Cell manufacturing | China, South Korea, Japan; growing in Europe and UK | Energy source used in manufacturing affects lifecycle emissions | | Battery pack assembly | Close to vehicle manufacturing plants | Transport emissions; pack-level quality control | | Recycling and second life | Emerging industry globally | Recovery rates still improving; infrastructure being built out | ### How is lithium actually extracted? There are two main extraction methods. In the salt flats of South America's "lithium triangle" (parts of Chile, Argentina, and Bolivia), lithium-rich brine is pumped to the surface and left to evaporate in large shallow ponds over many months, leaving a lithium-rich concentrate. This process uses relatively little energy but can consume large amounts of water in already arid regions, which is a serious local environmental concern. In Australia, lithium is mined from hard rock deposits called spodumene using conventional open-cast and underground mining. Hard rock mining is more energy-intensive to process but can be done with lower water use and in regions less water-stressed. ### Why is China so central to the supply chain? Even where lithium is mined elsewhere, the refining and processing steps that turn raw lithium into battery-grade lithium hydroxide or lithium carbonate are dominated by Chinese industry. China has invested heavily in both domestic and overseas processing capacity over the past two decades. Similarly, the major cell manufacturers are predominantly based in China, South Korea, and Japan. This concentration is a strategic concern for the UK, the EU, and the US, all of which are investing in domestic gigafactories and processing capacity to reduce dependence on any single country. The UK's own battery manufacturing ambitions centre on sites such as the planned Tata Energy gigafactory in Somerset. ### Is lithium mining bad for the environment? Lithium mining has real environmental costs, but context matters. Brine mining in Chile's Atacama has been linked to reduced water availability in one of the world's driest ecosystems, with documented effects on local flora and wetland habitats. Hard rock mining carries land disturbance and dust impacts. However, the comparison should always be made against the alternative: extracting, refining, and burning oil and gas at scale has its own substantial environmental and humanitarian footprint. Life-cycle assessments consistently find that EV batteries, despite their mining impact, result in lower overall environmental harm than combustion engines over a vehicle's life. The mining debate is real, but it should not be used to dismiss EVs wholesale. ### Is recycling improving the picture? Lithium recovery from spent batteries is becoming more viable commercially. Several UK and European companies are building capacity to recover lithium, cobalt, nickel, and manganese from end-of-life batteries, reducing the need for primary mining. EU battery regulations now require that new batteries incorporate minimum percentages of recycled materials, which will drive demand for recovered lithium. The UK is developing its own framework. Recovery rates from current recycling processes are not yet at the level needed to close the loop entirely, but the trajectory is in the right direction. Our [guides section](https://www.evchargecable.co.uk/blogs/guides) has more on EV battery recycling and what happens at end of life. ### Are there alternatives to lithium? Sodium-ion batteries are the most developed near-term alternative, and several manufacturers have announced sodium-ion models or confirmed plans to use sodium cells in entry-level EVs. Sodium is abundant and widely distributed globally, which would reduce supply chain concentration risk. Sodium-ion batteries currently have lower energy density than lithium-ion, meaning more weight for the same range, but the technology is improving rapidly. Solid-state batteries, which are further from mass production, could use less lithium or different materials entirely. The longer-term direction is toward chemistries that are less dependent on geographically concentrated critical minerals. ### Frequently asked questions #### Is there enough lithium in the world for all the EVs we need? Known global lithium reserves are large relative to near-term demand, but supply chain constraints (refining capacity, mining permits, infrastructure) create bottlenecks that can cause shortages. The industry is actively expanding mining and refining capacity, and improving recycling recovery rates will reduce dependence on primary supply over time. #### Does the UK produce any lithium? The UK has identified lithium deposits in Cornwall, where geothermal brines contain lithium alongside other minerals. A small number of companies are working to develop extraction processes from these brines. Commercial production would be modest relative to global scale, but it would provide some domestic supply and develop expertise in low-impact extraction techniques. #### How much lithium is in an EV battery? The quantity of lithium in a typical EV battery pack varies by battery size and chemistry, but a standard battery for a family car contains a meaningful but not enormous amount of lithium metal equivalent. Exact figures vary by model and chemistry; check the manufacturer's technical documentation if you need specifics for a particular vehicle. #### Is cobalt also a problem? Cobalt has been a significant concern due to its concentration in the Democratic Republic of Congo and documented artisanal mining practices. The battery industry has been actively reducing cobalt content in newer chemistries, particularly LFP (lithium iron phosphate) batteries, which contain no cobalt at all. Many new EV models use LFP or high-manganese chemistries to reduce or eliminate cobalt. #### What happens to EV batteries when they are recycled? End-of-life EV batteries are typically either repurposed for stationary energy storage (second-life use) or shredded and processed to recover materials including lithium, cobalt, nickel, and manganese. The recovered materials are fed back into the battery supply chain. Recycling processes are becoming more efficient, but a significant infrastructure build-out is still underway across Europe. #### Do I need to worry about the lithium supply chain when buying an EV? As an individual buyer, the supply chain is largely outside your control. The most meaningful thing you can do is support recycling by returning your battery for proper end-of-life processing, and factor battery longevity into how you charge and use your car. Keeping the battery healthy for as long as possible reduces the overall material footprint per kilometre driven. The lithium story is complex, but honest engagement with it is part of making an informed choice about EV ownership.
