(Bloomberg) -- The highest bid for lithium at an online sale surged by 140% in just six months, an indication the stampede for supplies of the main ingredient used in electric vehicle batteries could get even more intense.

Pilbara Minerals Ltd.’s auction of spodumene concentrate -- a partly-processed form of lithium -- attracted a top bid of $5,650 a ton on Wednesday for a cargo of 5,000 tons. That compares with $2,350 at the previous sale in late October on the Australian miner’s Battery Metal Exchange.
The surging prices are unnerving battery makers and EV firms. Tesla Inc. Chief Executive Officer Elon Musk said this month that lithium had gone to “insane levels” and is the “fundamental limiting factor” for EV adoption, adding the car giant might consider mining or refining it directly. Contemporary Amperex Technology Co. Ltd., the world’s largest battery maker, said last week it had won exploration rights for a lithium clay deposit in China.
“The pricing received on the BMX sales trading platform is indicative of the critical shortage that exists in respect of lithium raw material supply,” Pilbara Minerals said in a statement. It’s the company’s fourth online spodumene sale.
The jump in the auction bid is roughly in line with the increase in lithium carbonate -- a chemical used in battery production -- in China. It started rising in the middle of last year as the global recovery from the pandemic coincided with a surge in EV demand.
The rally has lost momentum in recent weeks -- prices are currently at 467,500 yuan ($71,182) a ton, according to Asian Metal Inc. -- as the worsening virus outbreaks upended supply chains and clouded the consumption outlook. The auction result suggests Chinese lithium compound prices are unlikely to drop below 400,000 yuan a ton, Daiwa Capital Markets’ analysts Dennis Ip and Leo Ho said in a note.
