The gold rush is back, but this time the focus is on “white gold” lithium – a major player in the world’s shift toward green energy.
The metal has been referred to as “the new gasoline” because of its use in electric vehicle batteries, but you can also find it in smartphones, laptops, Airpods, electric toothbrushes, smartwatches, e-cigarettes, pacemakers and other devices.
The metal is in the midst of a boom. Prices have surged roughly 500% year over year, triggering a global race to find and extract more.
While there’s an abundance within the U.S. – billions of dollars’ worth of the metal is believed to be contained in just one mine in Nevada – the country relies on imports. There are plans to open more mines in states like Nevada, California and North Carolina to help the U.S. reach supply goals.
“It’s funny how the development of this is just picked up immensely over the last four or five years. The lithium market was a pretty sleepy market for decades,” said Ken Hoffman, the co-head of consulting firm McKinsey & Company’s EV Battery Materials Research Group. “All of a sudden, the battery space really started to explode.”
Why is lithium important?
Lithium can be used in ceramics, greases and pharmaceuticals, but it’s best known as the material in batteries for cell phones, laptops and EVs. The rechargeable batteries take advantage of lithium’s light weight (it’s the lightest of all metals) and high electrochemical potential.
Production in 2021 was up 21% from the year prior while global consumption of lithium was up 33%, per the U.S. Geological Survey.
“One of the major reasons is because of those electric vehicles,” said Zhimin Xi, an associate professor at Rutgers’ department of industrial and systems engineering whose research interests include lithium-ion batteries.
EV sales doubled in 2021 to nearly 7 million units and have kept strong in 2022 as consumers turn toward vehicles that are more environmentally friendly.
Hoffman also noted that EV’s low maintenance and fuel costs are attracting buyers.
“There’s a lot of cost of ownership changes that people will see over time,” Hoffman said. “The reason why automotive companies are embracing this so much is it’s just a better, cheaper form of transportation.”
What country has the most lithium?
While the United States has significant lithium sources, it imports most lithium from countries like Argentina, Chile, China and Russia. The only domestic lithium production comes from one brine operation in Nevada.
But more U.S. production is on the horizon.
The Biden administration last year laid out a 10-year plan to incentivize more “safe, equitable and sustainable” domestic mining ventures for raw materials for lithium batteries.
“There is a race to capture the market,” reads the 2021 blueprint from the Federal Consortium for Advanced Batteries. “Strengthening and bolstering U.S. competitiveness in advanced battery innovation and manufacturing is vital.”
Is lithium expensive?
Lithium prices are up more than 500% year-over-year, according to an April report fromMcKinsey & Company.
That’s bad news for EV buyers looking for a deal. The average cost for lithium batteries is expected to jump in 2022 after falling for more than a decade in part due to supply chain issues. Just how much prices will increase by the end of the year is still up for debate, but some experts expect to see prices rise about 20%, per Axios.
Y. Shirley Meng, a professor of molecular engineering at the University of Chicago, said the price hike is likely temporary and won’t do much to tamper the rising demand for electric cars.
“That sets us back a little bit,” she said. But “people still think it’s more important that we reduce emissions as much as possible, even if it means they have to pay a little bit more.”
As for the price of consumer goods with smaller lithium-ion batteries like smartphones, experts say those prices should be more stable.
“For a lot of smaller-scale devices that you more regularly buy, like a cell phone or laptop, the batteries per unit energy or per unit mass are already priced in on the relatively higher side,” said Gary Koenig, an associate professor at the University of Virginia’s department of chemical engineering.
Will lithium supplies run out?
Lithium is more abundant than other popular metals like tin and silver, with over 39 million tons of lithium resources across the globe.
