Battery Metals: Lithium, Cobalt and Nickel

Copper, gold, and crude oil each have one dominant, liquid, exchange-traded reference price that the whole world quotes against. Lithium, cobalt, and nickel — the three metals at the heart of an electric-vehicle battery — do not, or at least didn't until recently, and each is a different story about why price discovery in a young, concentrated, chemically varied market looks nothing like a mature commodity exchange.

Three metals, three different problems

Lithium isn't a single commodity — it's several, since batteries need it in different chemical forms (carbonate, hydroxide) at different purities, and converting between forms costs money. There's no century-old exchange contract for lithium the way there is for copper; most is still sold on term contracts referencing price assessments from specialist reporting agencies. Exchange-traded lithium futures exist but remain thin relative to physical volumes.

Cobalt is overwhelmingly mined in one country (the Democratic Republic of Congo produces most world supply) and mostly comes out of the ground as a byproduct of copper or nickel mining, not as the primary target. Cobalt supply doesn't respond mainly to cobalt's own price — a copper mine keeps producing its copper-driven schedule regardless of what cobalt is worth, so cobalt supply is surprisingly inelastic, unlike a metal mined for its own sake.

Nickel has deep, established LME futures — but the contract specifies a grade ("Class 1") that battery precursor production mostly doesn't use; battery-grade nickel chemicals are typically made from "Class 2" nickel pig iron via a cheaper route. The 2022 LME nickel crisis, when prices doubled in hours and the exchange controversially cancelled trades, exposed exactly this mismatch: a squeeze in a thinly traded Class 1 contract most of the battery industry doesn't actually transact in.

Worked example

A battery maker needs 5,000 tonnes of lithium hydroxide for the quarter. Rather than hedge on an exchange, it negotiates a term contract referencing a published assessed price of $14,200/tonne, adjusted quarterly. If spot lithium rallies mid-quarter to an assessed $18,000/tonne, the buyer is insulated for that quarter, but has real exposure to the next reset — a very different risk profile from a copper buyer who could hedge years forward on a liquid futures curve.

For nickel, a producer buying nickel sulfate (a Class 2-derived product) can see its purchase cost move quite differently from the LME nickel price week to week, since the LME price reflects Class 1 supply-demand, while sulfate premiums reflect the separate, often tighter, Class 2 market.

What this means in practice

Anyone hedging or trading battery metals exposure needs to check which specific product form and which specific price reference their contract or futures position actually tracks — a mismatch between "the metal I'm exposed to" and "the price index I hedged with" is the single most common structuring error in this space, and it was precisely what turned a nickel price spike into an exchange-halting crisis in 2022.
