The supply of metal used for electric vehicles and computer batteries has been growing, but stocks of lithium companies are rallying as another mine shuts down.

The world’s largest battery maker CATL said it was suspending operations at a lithium mine in China, sending shares of other producers soaring on speculation that Beijing is moving to tackle industrial overproduction.

After soaring to record highs in 2022, prices of lithium, which is critical to the world's transition to greener energy, have tumbled almost 90%, prompting producers around the world to scale back investment plans.
