Highlights

  • Seaborne battery-grade hydroxide into China, Japan and Korea slipped another 0.9% to US$11.225/kg on 11 Nov, about 25% below early October.
  • Weak Demand for nickel-rich NCM cathodes, a glut-scare from China's revised lithium inventory data and restarting mines in Australia.
  • Hydroxide stays the weak sibling to carbonate until NCM demand recovers; watch China carbonate futures, cathode output schedules and Korean buying.

The lithium salt that feeds high-nickel batteries keeps sliding, and it is now cheaper than carbonate in the very ports where Asia's cathode makers buy it.

What happened

Battery-grade lithium hydroxide delivered into China, Japan and South Korea fell again on Wednesday. The CIF price averaged US$11.225/kg on 11 November, down 10 cents, or 0.9%, in a day, within a range of US$10.95 to US$11.50.

That is the same seaborne market the LME's hydroxide contract tracks. On 2 October the price stood at US$14.90/kg, which means buyers are now paying roughly a quarter less than six weeks ago.

Hydroxide is also now the cheaper lithium salt. Battery-grade carbonate into the same ports was assessed at US$12.35/kg on 11 November, while China's domestic carbonate price slipped 0.9% to CNY 90,450/t, down 21.6% in a month. That leaves hydroxide about US$1.13/kg below carbonate, an inversion that shows which battery chemistry buyers are backing.

Why it happened

The core problem is chemistry. Hydroxide is the preferred feed for nickel-rich NCM cathodes, and demand for them outside China remains subdued as carmakers diversify and cheaper LFP cells win more EV models. Overseas hydroxide prices fell 23.4% in October alone, slightly faster than carbonate's 22.1% drop.

Then came a confidence shock. In September the method for counting Chinese lithium stocks changed, and the estimate leapt to 175,000 tonnes from 78,800 tonnes. Chinese carbonate futures lost more than 14% in three days as traders questioned whether the market was far looser than they thought.

Supply is creeping back too. Mineral Resources has restarted its Bald Hill mine after an 18-month pause and Core Lithium has resumed work at Finniss, while the EU plans to cap Chinese EV imports at 350,000 units a year from next year, a potential hit to Chinese battery orders.

China's own hydroxide market offers no cushion. Sellers are quoting at discounts of CNY 4,000-9,000/t to the January carbonate futures contract, and buyers' psychological ceiling sits below CNY 84,000/t. Precursor production schedules for November were also cut notably.

How it plays out

Not every signal is negative. In October, Upstream salt inventories were reported at their lowest since April 2024, while material was piling up further down the chain in cathode plants and unsold EVs. One analyst called September's slide "more like a crisis of confidence than a collapse in lithium demand".

Chinese carbonate stocks are also falling. They stood at 125,391 tonnes last week, down 2,994 tonnes, and spot carbonate is expected to trade sideways between CNY 82,000 and 105,000/t in the short term. Year-end exports ahead of a Chinese tax-rebate change in January could add support.

For now the losers are hydroxide refiners, many of them Western-funded plants whose Business case assumed a high-nickel future. Winners are cathode makers locking in cheap feed, and LFP producers whose cost edge keeps widening. Chinese converters feel it too: the battery-grade hydroxide index for China fell US$125 to US$10,747/t on 11 November.

Next week, watch whether the CIF price holds above US$11/kg, whether Chinese carbonate futures stay near CNY 88,000-89,000/t, and any sign of Korean and Japanese restocking for 2027 contracts. A firm December cathode schedule would be the first hint the slide is ending.
