What is it?

Lithium (Li, atomic number 3) is the lightest metal and the least dense solid element. A bar of it floats on water and cuts with a knife. It holds the highest electrochemical potential of any element, which means a lithium cell stores more energy per unit of weight than any commercialised alternative.

That single property built the market. Everything else lithium does — ceramics, glass, greases, air treatment, pharmaceuticals — predates the battery and accounts for a minority of demand.

It trades in four principal forms:

• Spodumene concentrate, quoted at 6% Li₂O (SC6), the hard-rock product shipped from Australia, Zimbabwe, Brazil, and Mali.
• Brine concentrate, pumped and evaporated at the salar before chemical conversion.
• Lithium carbonate, the battery-grade chemical that prices the market and feeds lithium iron phosphate cells.
• Lithium hydroxide, preferred for high-nickel cathodes and priced at a premium or discount to carbonate depending on cathode mix.

How is it made?

brine → evaporation ponds or direct extraction → concentrate → carbonate plant → battery-grade chemical hard rock → flotation → spodumene concentrate → roasting → acid leach → carbonate or hydroxide

Two routes reach the same chemical. Brine operations in Chile and Argentina pump lithium-bearing groundwater into evaporation ponds and concentrate it over 12 to 18 months on sunlight alone, which is cheap and slow. Direct lithium extraction pulls the metal from brine in hours using sorbents, and the Andean and North American projects are built around it. Hard rock moves faster and costs more: spodumene ore floats to a 6% concentrate, roasts to convert the crystal structure, then leaches in sulfuric acid and crystallises into carbonate or hydroxide.

The conversion step decides the market. Roughly 70% of world refining and chemical capacity sits in China, so Australian, Zimbabwean, Brazilian, and Malian concentrate sails to Chinese converters regardless of who owns the mine.

Where is it produced?

USGS places 2025 world mine production at 290,000 tonnes of contained lithium, against 222,000 t in 2024. That 31% increase in a single year is the largest on this site.

Producer	2025 mine production	World share
Australia	92,000 t	31.7%
China	62,000 t	21.4%
Chile	56,000 t	19.3%
Zimbabwe	28,000 t	9.7%
Argentina	23,000 t	7.9%
Brazil	12,000 t	4.1%
Mali	9,400 t	3.2%
Other producers	7,600 t	2.6%

The growth spreads wide. China added 20,600 t in a year, Mali went from 770 t to 9,400 t as two operations started, Zimbabwe added 8,000 t, and Argentina rose 67%.

Reserves stand at 37 million tonnes and identified resources near 150 million, with the United States at 30 Mt, Argentina 28 Mt, Bolivia 23 Mt, Chile 13 Mt, and Australia and China 10 Mt each. Geology is abundant; permitting, water, capital, and conversion capacity are the constraints.

Notable sources & producers

Jianxiawo (CATL, Jiangxi)	A lepidolite mine whose ten-month suspension moved the world price.
Bikita and Arcadia (Zimbabwe)	Chinese-owned operations supplying roughly 15% of the concentrate China imports.
Goulamina (Mali)	One of two new operations that took Malian output from 770 t to 9,400 t in a year.
Chinese converters (Ganfeng, Tianqi, and peers)	Roughly 70% of world conversion capacity, and the step every mine depends on.
Thacker Pass and Salton Sea (United States)	Claystone and geothermal-brine projects behind 30 Mt of U.S. resources.

What is it used for?

• electric-vehicle batteries, the largest and fastest-growing use
• grid and commercial energy storage, at 15% of demand
• consumer electronics and portable power tools
• ceramics and heat-resistant glass, where lithium lowers firing temperature
• lubricating greases for high and low temperature service
• air treatment, metallurgy, and polymer catalysts
• pharmaceuticals, where lithium salts treat bipolar disorder

Why is it important?

Lithium is the constraint on stored electricity. Grid storage smooths intermittent generation and vehicles replace liquid fuel with charge, and both depend on a chemistry that leads every commercialised alternative on energy per kilogram.

The demand curve is steep and broad. Electric-vehicle sales pass 25 million units in 2026, and grid storage at 15% of lithium demand grows faster than any other segment. Each is a national infrastructure programme in a dozen countries at once, which makes the metal a policy object. Every major economy lists it as critical, and the competition runs through refining capacity and offtake contracts rather than through ore bodies.

Is there a substitute?

Sodium-ion is the real answer, and it arrives with a weight penalty.

Sodium-ion cells run on abundant, cheap feedstock and suit stationary storage where mass matters less, and Chinese manufacturers have commercialised them for grid and light-vehicle use. Energy density lands below lithium iron phosphate, which keeps passenger vehicles and portable electronics on lithium.

Outside the battery, USGS lists direct substitutes: calcium, magnesium, mercury, and zinc as anode material in primary batteries; calcium and aluminium soaps for stearates in greases; and sodic and potassic fluxes in ceramics and glass.

Within lithium, chemistry substitutes freely. Lithium iron phosphate uses carbonate and high-nickel cathodes use hydroxide, and the cathode mix shifts with price faster than any mine responds.

How is it transported?

mine or salar → concentrate or brine → port → bulk vessel or container → converter → carbonate or hydroxide → cathode plant → cell

Spodumene concentrate moves as dry bulk from Port Hedland, Fremantle, and Esperance to Chinese ports, and from Beira and Durban for Zimbabwean output. Andean brine concentrate trucks over the passes to Pacific ports before conversion in Chile or China.

The chemicals move in containers: carbonate in bulk bags and drums, hydroxide sealed against moisture and carbon dioxide. Finished cells carry the strictest rules in the chain, shipping under United Nations dangerous-goods classes with state-of-charge limits and air-freight restrictions.

Transportation risks

Chinese conversion capacity

Roughly 70% of world refining sits in one country, which places a processing step between every mine and every cell. A mine anywhere on earth reaches a battery through a converter that is Chinese seven times in ten, and that is the step conversion projects outside China are funded to duplicate.

Producer-country export policy

Zimbabwe suspended concentrate and raw mineral exports on February 25, 2026, pulling a January 2027 deadline forward to force domestic processing. The country supplies roughly 15% of the concentrate China imports, and Indonesia’s nickel precedent shows the model other producers hold.

Andean water and community agreements

Salar operations sit in the driest desert on earth on brine extraction rates set by permits and community agreements. Water is the binding local constraint, and it decides expansion timelines more than geology does.

Single-asset concentration

Greenbushes anchors Australian supply and Atacama anchors Chilean supply. The ten-month suspension of CATL’s Jianxiawo mine showed the effect: one asset standing down moved the world price by tens of percent.

How long does it store?

Lithium carbonate stores for years in sealed packaging at ambient conditions, and spodumene concentrate stores indefinitely. Lithium hydroxide is the exception: hygroscopic, absorbing carbon dioxide to form carbonate, it holds battery specification for roughly six to twelve months in sealed drums.

That asymmetry shapes the market. Buyers build carbonate inventory and buy hydroxide close to need, so a supply shock transmits into hydroxide prices faster than into carbonate.

Historical price behavior

Battery-grade lithium carbonate:

Period	Price
December 2022 peak	RMB 575,000/t (~$82,200/t)
2023–24 decline	to roughly $12,000/t
Mid-2025 trough	near $9,000/t
2026 rally	above $25,000/t
September 2, 2026 CIF Asia	$19,750/t
September 21, 2026, China	RMB 134,400/t

The 2022 peak came from vehicle demand outrunning a mine base that took three years to answer. The answer overshot. Australian, Chinese, African and South American supply arrived together, world production rose 31% in 2025 alone, and carbonate lost roughly 90% of its peak value.

The 2026 move reversed part of that on supply withdrawal rather than demand. Zimbabwe’s export suspension and the Jianxiawo stand-down lifted prices more than 170% off the trough, and the market gave back 16% in the month to September 21.

Current price & market — September 21, 2026

Market reference	Current level
Battery-grade carbonate, CIF Asia	$19,750/t
Battery-grade carbonate, China	RMB 134,400/t
Month-over-month change	−16%
Year-over-year change	+82%
Spodumene concentrate, 6% Li₂O FOB Australia	$2,254/t

The market is pricing two forces against each other. Mine supply grew 31% in 2025 and keeps expanding across Australia, Africa, and South America, while policy and single-asset outages pull tonnes back out. The result is an 82% year-over-year gain alongside a 16% monthly decline.

Demand holds its slope, which keeps the multi-year balance tightening while spot swings. Refining is where the capital goes: conversion projects outside China are funded and building in Australia, Europe, and North America, reaching scale on a timeline measured in years.

Price note: Chinese domestic carbonate in RMB, CIF Asia carbonate in dollars, hydroxide, and spodumene concentrate each measure a different product, currency, and delivery point, and move on their own basis. Concentrate prices follow chemical prices with a lag set by shipping and conversion time.

Strategic risks

1. Refining concentration near 70% in one country, which applies to every mine regardless of ownership.
2. Producer-country export policy, where Zimbabwe’s February 2026 suspension sets a template others hold.
3. Single-asset concentration at Greenbushes, Atacama, and Jianxiawo.
4. Price volatility that swings project economics between funded and shelved within a year.
5. Water and community agreements setting the pace of Andean expansion.
6. Hydroxide’s storage life, which removes stockpiling as a buffer for high-nickel cathode makers.
7. Sodium-ion substitution in stationary storage, which caps lithium’s upside in the fastest-growing demand segment.
8. Conversion projects outside China reaching scale on a multi-year timeline.

What can move the market?

• Chinese cell production rates and cathode chemistry mix
• electric-vehicle sales and subsidy policy in China, Europe, and the United States
• grid-storage procurement and interconnection queues
• recycling volumes as the first large cell cohorts retire
• Zimbabwe’s export suspension and similar producer-country measures
• Jianxiawo and other Chinese lepidolite operating rates
• Australian spodumene shipments and SC6 contract settlements
• Chilean state participation and SQM and Albemarle output
• Argentine brine ramp rates and direct-extraction commissioning
• conversion capacity commissioned outside China
• carbonate-to-hydroxide spread and cathode demand mix
• sodium-ion commercialisation in stationary storage
• USGS and Chinese production revisions

Lithium prices respond to conversion availability and policy announcements faster than to mined tonnes, because the ore is abundant and the processing is scheduled.

Xin.bz bottom line

Lithium is the metal that stores electricity, and its mine supply has expanded faster than that of any other commodity on this site.

Production rose 31% in a single year to 290,000 tonnes. Mali became a meaningful producer in twelve months, Zimbabwe and Argentina added double digits, and reserves stand at 37 million tonnes against resources near 150 million. The geology question is settled.

The processing question is open. Roughly 70% of conversion capacity sits in China, so the diversification achieved at the mine ends one step short of the chemical. Spodumene from Western Australia, brine from the Atacama, concentrate from Zimbabwe and Mali: four continents of rock and salt converge on the same set of plants.

Price behaviour follows that shape. A market with abundant ore and concentrated processing prices policy and outages rather than reserves. Carbonate fell 90% from its peak on new supply, then gained 170% on an export ban and one suspended mine.

Lithium is the commodity where mine supply diversified across four continents and refining capacity stayed in one.
