How new lithium extraction technology could help us meet electric vehicle targets

The world contains vast quantities of lithium, an integral element in electric vehicle batteries. And though lithium is commonly mined from hard rock, the majority of the world’s lithium reserves are actually found in brine, extremely salty water beneath the Earth’s surface.

Today, brine mining involves evaporating the brine in massive, extravagantly colored pools over a series of about 18 months, leaving high concentrations of lithium behind. It’s a simple but inefficient process that takes up vast swaths of land and is ecologically disruptive.

As automakers around the world struggle to meet extraordinarily ambitious electric vehicle production targets, there’s growing interest in doing things differently.

“The auto industry requires a 20x increase in lithium supply, and there’s just no way to achieve that type of growth with conventional technologies,” said Dave Snydacker, founder and CEO of Lilac Solutions.

Lilac is one of a number of companies piloting a set of new and largely unproven technologies called direct lithium extraction, or DLE, which could increase the efficiency and decrease the negative externalities of the brine mining process.

Instead of concentrating lithium by evaporating brine in large pools, DLE pulls the brine directly into a processing unit, puts it through a series of chemical processes to separate the lithium, then injects it back underground. This process produces battery-grade lithium carbonate or hydroxide in a matter of hours, without the need to transport concentrated brine to a separate processing facility.

DLE could also help jump-start the domestic lithium mining market. Today, most lithium brine mining takes place in the Salar de Atacama, an expansive salt flat in northern Chile that contains the highest quality lithium brine in the world. But DLE technologies require much less land and can help unlock resources in areas where the brine contains less lithium and more impurities.

North American companies Lilac Solutions, EnergyX and Standard Lithium are exploring lithium resources in areas such as Arkansas’ Smackover Formation, California’s Salton Sea and Utah’s Great Salt Lake, as well as abroad in Argentina, Bolivia and Chile. The Chilean government has even announced that all new lithium projects will be required to use DLE technology.

“So the timing is right and ripe for this to see the light of day very, very soon,” said Amit Patwardhan, CTO of EnergyX.

Direct lithium extraction company EnergyX is building demonstration plants in Argentina, Chile, California, Utah and Arkansas.

Doing things differently

In a world before electric vehicles, traditional methods of brine mining and hard rock mining more than sufficed to meet global lithium demand.

“The world didn’t need DLE for the last 50 years. Lithium’s primary use was industrial — ceramics, glass and lubricants,” said Robert Mintak, CEO of Standard Lithium.

But with demand for EVs and the lithium-ion batteries that power them booming, now there’s a supply crunch.

“Over the last 10 years, 90% of new lithium production has come from hard rock projects. But hard rock projects are increasingly expensive as we go into lower grade resources. And if you add up all the hard rock projects, there’s just not enough resource out there to meet automaker goals. It’s the brine resources that are large enough to electrify the vehicle industry,” Snydacker said.

DLE is already being used to some extent in both Argentina and China, where the companies Livent and Sunresin are implementing commercial tech that combines DLE with traditional evaporation pond operations.

These companies both rely on a technology called adsorption, the only commercially proven approach to DLE. In this process, lithium molecules in the brine adhere to an adsorbant substance, removing them from surrounding impurities. But experts say that stripping the lithium from the adsorbents requires a lot of fresh water, a big problem considering many of the world’s best brine resources are in arid areas.

Livent’s most recent sustainability report indicates that it uses 71.4 metric tons of fresh water per metric ton of lithium carbonate equivalent, or LCE, produced. Lilac reported that in pilot testing it uses between 10 and 20 metric tons of fresh water, while EnergyX says it uses less than 20 metric tons.

China-based Sunresin says that it recycles all of its fresh water, and that its newer projects will operate without evaporation ponds.

But a host of other companies are now getting into the industry, testing out alternative technologies which they claim will not only eliminate evaporation ponds altogether, but increase yields while lowering energy and fresh water requirements.

New players

Bay Area-based Lilac Solutions is using a technology called ion exchange. It’s currently piloting its tech in Argentina in partnership with Australian lithium company Lake Resources.

“With the Lilac ion-exchange bead we’ve developed a ceramic material. This ceramic selectively absorbs lithium from the brine while releasing a proton. Once the lithium is absorbed into the material, we then flush the lithium out of the bead using dilute acid and that produces a lithium chloride concentrate which can be easily processed into battery grade chemicals,” Snydacker explained.

Lilac Solutions is developing a direct lithium extraction facility in Argentina in partnership with Australian lithium company Lake Resources.

Lilac expects to have its first commercial-scale module operating before the end of 2024. The company is backed by BMW and the Bill Gates-funded Breakthrough Energy Ventures, and Ford has signed a nonbinding agreement to buy lithium from its Argentina plant.

EnergyX, which is based out of both San Juan, Puerto Rico, and Austin, Texas, uses a combination of technologies that it can tailor to the specific brine resource. Step one is traditional adsorption, followed by a method known as “solvent extraction,” in which the concentrated brine is mixed with an organic liquid. The lithium is then transferred to the organic before it’s stripped free and concentrated. Membrane filtration is the final stage, which removes all remaining impurities.

“So you see these all these loops and synergies that come out of combining these technologies. And that is another big differentiator in what EnergyX does and what really drives the cost of the technology much lower compared to anybody else,” said Patwardhan.

EnergyX is building demonstration plants with undisclosed partners in Argentina, Arkansas, Chile, California and Utah, and is aiming to have the first two up and running by the end of this year. Recently, the company secured $50 million in funding from GM to help scale its tech.

Vancouver-based Standard Lithium also has big backers. The public company’s largest investor is Koch Industries, and it’s been running a demonstration plant in South Arkansas for the last three years, producing lithium at a preexisting bromine plant.

The company uses both ion-exchange and adsorption technologies, depending on the resource. It expects to begin construction on a commercial-scale DLE facility next year and is expanding into Texas as well.

“We have an opportunity as we expand from Arkansas to Texas to be the largest producing area for lithium chemicals in North America, utilizing in an area that’s not under water stress, that has a social license to operate,” said Mintak.

Companies such as Standard Lithium, which are leaning into the U.S. market, stand to benefit from the Inflation Reduction Act, which ties electric vehicle subsidies to domestic sourcing of battery materials. Automakers can also receive the full EV credit if they source from countries that have free trade agreements with the U.S., such as Chile.

While Chile has announced that all new lithium projects in the country will be required to use DLE technologies, it has not announced what companies it will be partnering with for these new projects.

Neighboring Bolivia was considering technology from both EnergyX and Lilac Solutions to help unlock the country’s vast but largely undeveloped lithium resources. The government ultimately tapped a consortium of Chinese companies, led by battery giant CATL, to spearhead DLE efforts in its salt flats.

Most new lithium supply will continue to come from hard rock projects for the rest of this decade, Snydacker said. “But by the end of this decade, we’ll see very large-scale brine projects coming online …” he predicted. “And going out into the next decade, this technology will provide a majority of new supply.”

Overall, lithium production from DLE is projected to grow from about 54,000 metric tons today to 647,500 metric tons by 2032, according to Benchmark Mineral Intelligence. That’s forecast to be worth about $21.6 billion.

“But when we place it in relative terms against the rest of the global market, that only represents around 15% of total supply,” said James Mills, principal consultant at Benchmark Mineral Intelligence. “So we’re still going to have to rely on traditional forms of production for the lithium units, whether it’s evaporation ponds or hard rock mining.”

Apple's market share slides in China as iPhone shipments decline, analyst Kuo says

Apple is losing market share in China due to declining iPhone shipments, supply chain analyst Ming-Chi Kuo wrote in a report on Friday. The stock slid 2.4%.

“Apple has adopted a cautious stance when discussing 2025 iPhone production plans with key suppliers,” Kuo, an analyst at TF Securities, wrote in the post. He added that despite the expected launch of the new iPhone SE 4, shipments are expected to decline 6% year over year for the first half of 2025.

Kuo expects Apple’s market share to continue to slide, as two of the coming iPhones are so thin that they likely will only support eSIM, which the Chinese market currently does not promote.

“These two models could face shipping momentum challenges unless their design is modified,” he wrote.

Kuo wrote that in December, overall smartphone shipments in China were flat from a year earlier, but iPhone shipments dropped 10% to 12%.

There is also “no evidence” that Apple Intelligence, the company’s on-device artificial intelligence offering, is driving hardware upgrades or services revenue, according to Kuo. He wrote that the feature “has not boosted iPhone replacement demand,” according to a supply chain survey he conducted, and added that in his view, the feature’s appeal “has significantly declined compared to cloud-based AI services, which have advanced rapidly in subsequent months.”

Apple’s estimated iPhone shipments total about 220 million units for 2024 and between about 220 million and 225 million for this year, Kuo wrote. That is “below the market consensus of 240 million or more,” he wrote.

Apple did not immediately respond to CNBC’s request for comment.

Amazon to halt some of its DEI programs: Internal memo

Amazon said it is halting some of its diversity and inclusion initiatives, joining a growing list of major corporations that have made similar moves in the face of increasing public and legal scrutiny.

In a Dec. 16 internal note to staffers that was obtained by CNBC, Candi Castleberry, Amazon’s VP of inclusive experiences and technology, said the company was in the process of “winding down outdated programs and materials” as part of a broader review of hundreds of initiatives.

“Rather than have individual groups build programs, we are focusing on programs with proven outcomes — and we also aim to foster a more truly inclusive culture,” Castleberry wrote in the note, which was first reported by Bloomberg.

Castleberry’s memo doesn’t say which programs the company is dropping as a result of its review. The company typically releases annual data on the racial and gender makeup of its workforce, and it also operates Black, LGBTQ+, indigenous and veteran employee resource groups, among others.

In 2020, Amazon set a goal of doubling the number of Black employees in vice president and director roles. It announced the same goal in 2021 and also pledged to hire 30% more Black employees for product manager, engineer and other corporate roles.

Meta on Friday made a similar retreat from its diversity, equity and inclusion initiatives. The social media company said it’s ending its approach of considering qualified candidates from underrepresented groups for open roles and its equity and inclusion training programs. The decision drew backlash from Meta employees, including one staffer who wrote, “If you don’t stand by your principles when things get difficult, they aren’t values. They’re hobbies.”

Other companies, including McDonald’s, Walmart and Ford, have also made changes to their DEI initiatives in recent months. Rising conservative backlash and the Supreme Court’s ruling against affirmative action in 2023 spurred many corporations to alter or discontinue their DEI programs.

Amazon, which is the nation’s second-largest private employer behind Walmart, also recently made changes to its “Our Positions” webpage, which lays out the company’s stance on a variety of policy issues. Previously, there were separate sections dedicated to “Equity for Black people,” “Diversity, equity and inclusion” and “LGBTQ+ rights,” according to records from the Internet Archive’s Wayback Machine.

The current webpage has streamlined those sections into a single paragraph. The section says that Amazon believes in creating a diverse and inclusive company and that inequitable treatment of anyone is unacceptable. The Information earlier reported the changes.

Amazon spokesperson Kelly Nantel told CNBC in a statement: “We update this page from time to time to ensure that it reflects updates we’ve made to various programs and positions.”

Read the full memo from Amazon’s Castleberry:

Team,

As we head toward the end of the year, I want to give another update on the work we’ve been doing around representation and inclusion.

As a large, global company that operates in different countries and industries, we serve hundreds of millions of customers from a range of backgrounds and globally diverse communities. To serve them effectively, we need millions of employees and partners that reflect our customers and communities. We strive to be representative of those customers and build a culture that’s inclusive for everyone.

In the last few years we took a new approach, reviewing hundreds of programs across the company, using science to evaluate their effectiveness, impact, and ROI — identifying the ones we believed should continue. Each one of these addresses a specific disparity, and is designed to end when that disparity is eliminated. In parallel, we worked to unify employee groups together under one umbrella, and build programs that are open to all. Rather than have individual groups build programs, we are focusing on programs with proven outcomes — and we also aim to foster a more truly inclusive culture. You can read more about this on our Together at Amazon page on A to Z.

This approach — where we move away from programs that were separate from our existing processes, and instead integrating our work into existing processes so they become durable — is the evolution to “built in” and “born inclusive,” instead of “bolted on.” As part of this evolution, we’ve been winding down outdated programs and materials, and we’re aiming to complete that by the end of 2024. We also know there will always be individuals or teams who continue to do well-intentioned things that don’t align with our company-wide approach, and we might not always see those right away. But we’ll keep at it.

We’ll continue to share ongoing updates, and appreciate your hard work in driving this progress. We believe this is important work, so we’ll keep investing in programs that help us reflect those audiences, help employees grow, thrive, and connect, and we remain dedicated to delivering inclusive experiences for customers, employees, and communities around the world.

#InThisTogether,

Candi

Tesla is voluntarily recalling about 239,000 of its electric vehicles in the U.S. to fix an issue that can cause its rearview cameras to fail, the company disclosed in filings posted Friday to the National Highway Traffic Safety Administration’s website.

“A rearview camera that does not display an image reduces the driver’s rear view, increasing the risk of a crash,” Tesla wrote in a letter to the regulator. The recall applies to Tesla’s 2024-2025 Model 3 and Model S sedans, and to its 2023-2025 Model X and Model Y SUVs.

The company also said in the acknowledgement letter that it has already “released an over-the-air (OTA) software update, free of charge” that can fix some of the vehicles’ camera issues.

In 2024, Tesla issued 16 recalls in the U.S. that applied to 5.14 million of its EVs, according to NHTSA data. The recall remedies included a mix of over-the-air software updates and parts replacements. More than 40% of last year’s recalls pertained to issues with the newest vehicle in the company’s lineup, the Cybertruck, an angular steel pickup that Tesla began delivering to customers in late 2023.

Regarding the latest recall, the company said it had received 887 warranty claims and dozens of field reports but told the NHTSA that it was not aware of any injurious, fatal or other collisions resulting from the rearview camera failures.

Other customers with vehicles that “experienced a circuit board failure or stress that may lead to a circuit board failure,” which cause the backup camera failures, can have their vehicles’ computers replaced by Tesla, free of charge, the company said.

Tesla did not immediately respond to CNBC’s request for comment.
