Lithium Hydroxide
A refined lithium chemical preferred for high-nickel NMC and NCA battery cathodes, typically commanding pricing distinct from lithium carbonate and more closely tied to premium, longer-range EV battery demand.

Overview
Lithium hydroxide (LiOH) is a white, caustic lithium chemical used mainly as the lithium source in high-nickel cathode chemistries — NMC (nickel-manganese-cobalt) and NCA (nickel-cobalt-aluminium) — favored in longer-range electric vehicles because they pack more energy into the same battery weight than lithium iron phosphate cells do. It's more reactive and harder to handle safely than lithium carbonate, and it's typically produced either directly from spodumene concentrate or by converting lithium carbonate into hydroxide through an additional chemical step, part of why hydroxide has historically traded at a premium to carbonate.
How It's Manufactured
Hydroxide can be made directly from spodumene concentrate — roasting and leaching it, similar to the carbonate process, but finishing with a step that crystallizes lithium hydroxide monohydrate rather than carbonate — or it can be produced by taking already-refined lithium carbonate and reacting it with lime (calcium hydroxide) in a process called causticization, which converts the carbonate into hydroxide and precipitates calcium carbonate as a byproduct. The causticization route lets producers add hydroxide capacity without needing fresh spodumene feedstock, part of why it has become common as battery-grade hydroxide demand has grown faster than direct-production capacity.
Byproducts
The causticization conversion route produces calcium carbonate as its main byproduct, sometimes sold into other industrial uses but often simply a low-value waste stream to dispose of. Direct production of hydroxide from spodumene generates the same type of leaching-stage waste and tailings as lithium carbonate production from hard rock, since the front end of the process — crushing, roasting and acid leaching of the spodumene — is essentially identical up until the final precipitation step, where the process branches toward carbonate or hydroxide depending on which chemical is added.
Who Consumes It
Battery cathode manufacturers making NMC and NCA cells are lithium hydroxide's dominant customers, concentrated among cell makers supplying premium and longer-range EVs — companies like LG Energy Solution, Samsung SDI and Panasonic have historically been larger hydroxide buyers than the LFP-focused Chinese battery majors, though that gap has narrowed as Chinese cell makers have diversified into high-nickel chemistries too. Hydroxide demand tracks the premium, longer-range end of the EV market specifically, rather than EV demand overall, which is why it has moved somewhat differently from carbonate demand in recent price cycles.
Everyday Uses
A consumer with a longer-range electric vehicle, one built around NMC or NCA cells rather than LFP, is very likely relying on lithium hydroxide somewhere in that battery's supply chain. Outside batteries, lithium hydroxide has a much older, smaller-scale industrial use as a thickener in high-performance lubricating greases, valued for holding up under heat and moisture better than greases made with other thickeners — an application that predates the battery boom by decades but is now a minor fraction of total hydroxide demand.
Industrial Uses
Beyond cathode manufacturing, lithium hydroxide is used industrially to make lithium-based greases for automotive, aerospace and heavy-machinery applications, and as a carbon dioxide scrubber in confined-air systems such as submarines and spacecraft, where its ability to absorb CO2 makes it valuable for life-support systems. These non-battery industrial uses were lithium hydroxide's primary demand driver before the EV era, but battery cathode production now accounts for the overwhelming majority of global hydroxide consumption and is what determines pricing and investment in new hydroxide capacity.

China's Lithium Inventories Fall 10% as Price Cushion Narrows
China's combined lithium carbonate and lithium hydroxide inventories fell 10% year-to-date through August 2026, leaving the market with a thinner cushion against supply disruptions even as new spodumene imports have already pulled prices back down.
Critical Minerals Investment Fell 9% in 2025 -- One Fix Is Squeezing More From Mines Already Running
IEA data shows critical minerals investment fell 9% in 2025 even as demand keeps climbing. An ABB executive argues upgrading mines already producing, not just building new ones, can add supply faster.
India Doesn't Need Its Own Lithium Mines to Build a Lithium Market, Researchers Argue
Researchers argue India can build a domestic critical-minerals market through import-led trading on exchanges like MCX, similar to how it trades imported crude oil and gold, without first developing lithium mines of its own.
Albemarle Stock Falls 4.5% as Lithium Prices Soften Again, Even After a 20-Fold Profit Jump
Albemarle stock dropped 4.45% as lithium prices softened again sector-wide, even after average prices rose 61% year-over-year and profit jumped more than 20-fold last quarter.
BMI Raises Its 2026 Lithium Price Forecast, But Warns the Rally Has Already Outrun Fundamentals
BMI raised its 2026 lithium carbonate forecast to $20,100 a tonne on strong battery-storage demand, but warns current spot prices have run ahead of fundamentals.
Lithium's Supply Deficit Now Expected in 2030, Analysts Say, as Australian Lithium Stocks Split on the Outlook
Shanghai Metals Market now expects lithium's next supply deficit in 2030, not sooner, as a sulphuric-acid cost shock and split ASX broker ratings on Pilbara Minerals, IGO Limited and Core Lithium reshape the outlook.
Lithium Spot Prices Are Falling, But the Forward Curve Is Pricing In a Very Different Story
Benchmark's forward curve shows spodumene in moderate contango, with 3-12 month lithium prices up $850-$2,787/t even as spot carbonate, hydroxide and spodumene all eased into August.
