Lithium at two-year low hobbles US bid to loosen China’s grip on market

The lowest lithium prices in over two years are hampering a handful of miners that want to challenge China’s dominance in the market.

China controls most of the processing that makes the mineral usable in rechargeable batteries, leaving American vehicle makers vulnerable to supply disruptions if trade tensions escalate. With automakers from Tesla to General Motors aiming to manufacture more electric cars at home, small companies are seeking to build the first US lithium mines in decades as a step toward forming a local supply chain.
