SANTIAGO (Reuters) - Chilean lithium miner SQM said on Monday that it had reached a long-term supply deal with Hyundai and Kia to provide the carmakers with the white metal, key for the production of electric vehicle batteries.

Hyundai and Kia will "secure a portion of (their) future lithium hydroxide supple from SQM," the miner said in a statement.
