Chinese lithium giant Ganfeng Lithium said Wednesday that industry inventories for both lithium ore and processed salts have fallen to historical lows, signaling a deepening supply deficit just as global producers commit billions to new production.
"Lithium demand has been compounding at incredible rates for the past five years or so now," Brian Dalton, CEO of Altius Minerals, said on the company's Q1 2026 earnings call. "Rather than beginning to succumb to the law of large numbers, as many have been calling for, demand appears actually to be instead accelerating."
The supply response is ramping up globally. Lithium Argentina announced this week it received key government approval for a 45,000 tonne-per-annum Stage 2 expansion of its Caucharí-Olaroz operation. Standard Lithium is advancing its Southwest Arkansas project toward a final investment decision in 2026, while operators of at least four other major projects from Mali to Brazil have confirmed expansion plans, according to Altius.
The tight market balance underscores the challenge facing the energy transition, where lithium is a critical input for electric vehicle batteries and grid-scale energy storage. With inventories depleted, the market is highly sensitive to any supply disruptions, while the success of multi-billion dollar expansion projects becomes critical to meeting demand growth that is now diversifying beyond EVs.
A Global Rush to Expand
The race to increase supply is evident across the industry. Lithium Argentina's approval for its Stage 2 expansion under the country's RIGI incentive regime will more than double the capacity of its Caucharí-Olaroz project, which currently stands at 40,000 tonnes per annum. The company noted the expansion will be supported by strong cash flow from its existing Stage 1 operations.
In the U.S., Standard Lithium is finalizing offtake agreements and vendor contracts for its Southwest Arkansas project, which will tap the Smackover formation. The company expects to begin construction in 2026 and achieve first commercial production in 2029. "We are running a competitive process to finalize our offtake agreements," CEO David Park told analysts, noting the significant rally in lithium prices has brought more buyers to the table.
Demand Diversifies Beyond EVs
While electric vehicles have been the primary driver of lithium demand, the market is broadening. Industry executives point to the rapidly growing need for battery energy storage systems (BESS) to support renewable power grids.
"The sources of the demand growth are also becoming more diversified beyond electric vehicle-based dominance, with the most notable new driver being the increasing addition of battery storage pairings to the rapidly expanding global fleet of renewable electricity plants," Altius's Dalton noted. This trend adds another layer of demand pressure on an already constrained supply chain, reinforcing the urgency behind the current wave of project expansions.
