Battery Supply Chain Glossary
The definitive guide to critical minerals, battery materials, and energy transition terminology from the world's most trusted source of lithium ion battery supply chain intelligence.
Lithium
Lithium is the lightest metal on the periodic table and the key raw material in rechargeable lithium ion batteries that power electric vehicles, energy storage systems, and consumer electronics. Global demand for lithium has surged as the energy transition picks up speed, production must triple by 2030 to meet forecast battery demand.

The lithium market is complex. Prices swing wildly based on supply additions, production costs, and downstream demand from gigafactories. Understanding lithium's supply chain, from brine pools in Chile's Atacama Desert to hard rock mines in Western Australia, is critical for anyone buying, selling, or investing in this metal.

What is Lithium?
Lithium (Li, atomic number 3) is an alkali metal with exceptional electrochemical properties. It's the most electropositive and least dense metal, which makes it perfect for rechargeable batteries. When lithium ions move between a battery's anode and cathode, they store and release energy efficiently.
In nature, lithium never exists as a pure metal - it's too reactive. Instead, it's found in mineral deposits (primarily spodumene) or dissolved in underground brine reservoirs. After extraction, lithium is refined into battery-grade chemicals: lithium carbonate (Li₂CO₃) or lithium hydroxide (LiOH).
Battery-grade lithium carbonate and hydroxide must meet purity standards above 99.5%. Lower-grade lithium goes into ceramics, glass, and lubricating greases - important markets, but minor compared to batteries. By 2030, batteries will account for over 95% of lithium demand.
What is lithium used for in batteries?
Lithium is the key active material in lithium ion batteries that power electric vehicles, energy storage systems, and consumer electronics. Lithium ions move between the battery's anode and cathode during charging and discharging, storing and releasing energy. Each EV battery pack contains 8-10 kg of lithium carbonate equivalent (LCE). Batteries now account for over 85% of global lithium demand.

Lithium Supply Chain: From Mine to Battery
The lithium supply chain splits into two main extraction routes: hard rock mining and brine extraction.
Hard rock mining dominates global supply. Australia produces roughly 50% of the world's lithium, mostly from spodumene ore mined in Western Australia. Spodumene concentrate (typically 5.5-6% lithium oxide) is shipped to China, where it's converted into lithium carbonate or hydroxide through energy-intensive roasting and chemical processing. This route is faster to bring online than brine but carries higher production costs.
Brine extraction is concentrated in South America's "Lithium Triangle", Chile, Argentina, and Bolivia. Brine is pumped from underground aquifers into massive evaporation ponds. Over 12-18 months, sun and wind evaporate the water, concentrating lithium salts. The process is cheaper than hard rock but slower to scale and more vulnerable to weather. Chile's SQM and Albemarle dominate brine production, but new projects in Argentina are ramping up fast.
Direct lithium extraction (DLE) technology is emerging as a third route. DLE uses ion exchange or adsorption to pull lithium directly from brine without evaporation ponds. It's faster, uses less land, and can tap lower-grade resources but commercial-scale DLE is still proving itself. If DLE works at scale, it could reshape the supply map by 2030.
Once refined into carbonate or hydroxide, lithium chemicals move to cathode and precursor manufacturers. China controls roughly 70% of global lithium refining capacity and dominates cathode active material (CAM) production. Western countries are racing to build domestic refining, but China's lead is enormous.
From there, cathodes go to battery cell producers. The same cathode chemistry dictates which lithium compound is used: LFP batteries need lithium carbonate, while NMC and NCA batteries require lithium hydroxide. Each EV battery pack contains 8-10 kg of lithium.
Lithium Applications: Where Does It Go?
Batteries now consume 85% of lithium production - a share that keeps growing. Here's the breakdown:
Electric vehicles are the biggest driver. A single EV battery pack needs 8-12 kg of lithium carbonate equivalent (LCE), depending on battery size and chemistry. Global EV sales hit 14 million units in 2024 and are forecast to exceed 30 million by 2030. That translates to insatiable lithium demand.
Battery energy storage systems (BESS) are the second-largest battery market. Grid-scale storage projects use lithium ion batteries to smooth renewable energy supply. As wind and solar capacity expands, BESS demand is growing even faster than EV demand in percentage terms.
Consumer electronics laptops, phones, power tools still consume significant lithium, though growth has plateaued. These products use smaller batteries but in massive volumes. Legacy demand from electronics won't disappear, but it's being dwarfed by EVs.
Non-battery applications include air conditioning, glass ceramics, pharmaceuticals, and aluminum production. These markets are stable but shrinking as a percentage of total demand. By 2035, battery demand will account for over 98% of lithium consumption.

Lithium Prices: Market Dynamics
Lithium prices are notoriously volatile. Between 2021 and 2023, lithium carbonate prices in China skyrocketed from $10,000/t to over $80,000/t, then crashed back to $12,000/t by late 2024. This boom-bust cycle reflects structural imbalances between supply, demand, and inventory.
Benchmark publishes the industry's most trusted lithium price assessments - IOSCO Type 2 assured and used globally for contract indexation. Our prices cover:
Lithium carbonate: Battery-grade 99.5%, CIF Asia and domestic China
Lithium hydroxide: Battery-grade monohydrate, CIF Asia and domestic China
Spodumene concentrate: SC6.0 (6% Li₂O), CIF China
The lithium market trades on both spot and contract pricing. Long-term offtake agreements between miners and battery makers provide supply security but can lag spot market moves by months. Many contracts now use Benchmark's price assessments as the index.

Price drivers include:
Chinese production: China dominates lithium refining. When Chinese producers cut output (as they did in Q4 2024), global prices respond immediately.
Downstream demand: Gigafactory utilization rates dictate how much lithium refiners need. If EV sales slow, battery production falls, and lithium demand drops.
Inventory levels: The lithium market is opaque. Benchmark's monthly inventory tracker is the only public source tracking stocks across the supply chain.
New supply: Major mines in Australia and brine projects in Argentina are adding capacity in 2025-2027. Whether supply outpaces demand depends on EV adoption rates.
Lithium Market Outlook
Lithium demand will grow from roughly 1 million tonnes LCE in 2024 to over 3 million tonnes by 2030. That requires massive investment in new mines, refineries, and chemical plants. The question isn't whether demand will grow. The question is whether supply can keep up without triggering another 2021-style price spike.
Benchmark forecasts a balanced market through 2026, followed by tighter conditions as EV penetration in Europe and North America accelerates. After 2028, markets could tighten significantly if Western supply chain buildouts lag behind policy targets like the Inflation Reduction Act (IRA).
Geopolitics matter. The U.S. and Europe are pushing to reduce reliance on Chinese lithium refining through subsidies, tariffs, and domestic project support. But building a Western lithium supply chain will take a decade. Until then, China controls pricing power.
Lithium recycling will contribute secondary supply by 2030, but it won't be enough to dent primary demand. Batteries need 8-10 years to reach end-of-life, so recycled lithium supply won't ramp meaningfully until the mid-2030s.

What's the difference between lithium carbonate and lithium hydroxide?
Lithium carbonate (Li₂CO₃) and lithium hydroxide (LiOH) are both battery-grade lithium chemicals, but they're used in different battery chemistries. Lithium carbonate is used primarily in LFP (lithium-iron-phosphate) batteries, while lithium hydroxide is required for high-nickel NMC and NCA cathodes used in premium EVs. Hydroxide typically trades at a premium to carbonate due to higher production costs. Learn more about lithium prices.
