China’s CATL, the world’s largest supplier of EV batteries, announced a set of new incoming products Monday, including a battery it claims has set a “new global record for superfast charging technology.”

In a post on WeChat, the company — Contemporary Amperex Technology Company Ltd. — said that its second-generation Shenxing battery could add 520 km (323 miles) of driving range from just five minutes of charging time— only slightly longer than it takes to refuel gas cars.

This appears to put CATL’s fast charging ahead of that of Chinese EV giant and Tesla rival BYD, which last month surprised the industry with a charging system it claimed could add about 400 km in range to its batteries also in about 5 minutes. 

Some analysts were skeptical about BYD’s claims, noting potential technical hurdles and high costs. However, if proved feasible on a larger scale, the tech could help the EV industry alleviate consumer concerns about electric vehicle range and convenience. 

CATL’s latest claims would also place its cutting-edge charging speeds comfortably ahead of those of its Western competitors. Tesla’s latest superchargers can add up to 270 kilometers of range in 15 minutes, while Mercedes-Benz Group recently said one of its batteries can recharge up to 325 kilometers within 10 minutes.

The new Shenxing product is also the world’s first lithium iron phosphate battery with both an 800 km range and a 12C peak charging rate, CATL said. It added that the battery outperforms the industry’s highest current charging level in low-temperature environments of -10°C.

On Monday, CATL also revealed new batteries within its “Naxtra” series, which it said would be “the world’s first mass produced sodium-ion battery,” reducing the EV industry’s reliance on lithium. 

The company added that sodium-ion batteries could help decrease maintenance costs and are capable of performing in extreme temperatures of -40°C to +70°C. 

One of the Naxtra batteries was specifically for heavy-duty trucks, which the company said offers over eight years of service life while providing reduced lifecycle costs and higher efficiency than traditional lead-acid batteries. 

Shenzhen-listed shares of CATL were trading up about 1% on Tuesday.

Tesla shares fell almost 6% on Monday, a day ahead of the electric vehicle company’s first-quarter earnings report, as analysts fret over “ongoing brand erosion.”

The stock closed at $227.50 leaving it less than $6 above its low for the year on April 8. The shares are now down 44% for the year after wrapping up their worst quarter since 2022 in March. It’s the 12th time this year the stock has dropped by at least 5% in a single session.

CEO Elon Musk’s many distractions outside of Tesla, especially his role within the Trump administration, are in focus, along with the company’s progress on a long-delayed robotaxi and self-driving technology for its existing cars.

In the online forum that Tesla uses to solicit investor inquiries in advance of its earnings calls, more than 300 questions were submitted pertaining to Tesla’s self-driving systems, around 200 came in about the company’s Optimus humanoid robots in development, and more than 160 questions poured in about Musk individually. One investor asked, “What steps has the board of directors taken to mitigate the brand damage caused by Elon’s political activities?”

After spending $290 million to help return Trump to the White House, Musk is now leading an initiative to slash tens of thousands of federal jobs, sell off or end leases for federal office buildings, and reduce U.S. government capacity.

Musk’s politics and antics have elicited a massive backlash in Europe and parts of the U.S. This year, the company has been hit with waves of protests, boycotts and some criminal activity that targeted Tesla vehicles and facilities in response to Musk.

Earlier this month, Tesla reported 336,681 vehicle deliveries in the first quarter, a 13% decline from the same period a year earlier.

The company is expected to report revenue of $21.24 billion for the first quarter, according to LSEG, which would mark a slight drop from the same period last year. Analysts expect earnings per share of 40 cents. Investors will be paying particularly close attention to any commentary about Trump’s widespread tariffs and the potential impact on revenue and earnings as the year progresses.

Oppenheimer analysts wrote in a note out Monday that “ongoing brand erosion” for Tesla in the U.S. and Europe is weighing on sales already, but a “bigger issue for the company is potential weakness in China demand and margin impact due to the Trump tariffs.”

They wrote that competition in China, coupled with “nationalistic” consumer trends there, could “drive sales toward domestic brands.” Tesla would then have to export more of its China-made cars, which could lead to “downward pressure on pricing,” the Oppenheimer analysts said.

Caliber, a research firm that tracks how U.S. consumer sentiment is shifting around major brands, found that only 27% of its survey respondents in March would consider purchasing a Tesla, compared to 46% in January 2022.

Wedbush Securities analyst Dan Ives, a longtime Tesla bull, is hoping for a “turnaround vision” from Musk on Tuesday’s earnings call.

“Tesla has now unfortunately become a political symbol globally of the Trump Administration/DOGE,” he wrote, noting that “Tesla’s stock has been crushed since Trump stepped back into the White House.”

Ives estimated 15% to 20% “permanent demand destruction for future Tesla buyers due to the brand damage Musk has created” by working for Trump.

Late last week, Barclays maintained the equivalent of a sell rating and slashed its price target on Tesla to $275 from $325, citing a “confusing set-up” on the first-quarter with “weak fundamentals.” The firm said it could see a positive reaction if Musk is more focused on his automaker, and depending on what the company discloses about an anticipated “FSD event,” referring to Tesla’s Full Self-Driving offering.

Tesla said in announcing its reporting date that, in addition to earnings, it will provide a “live company update,” language the company hasn’t typically used in disclosures.

As Google heads back to the courtroom Monday, the company is arguing that the U.S. needs the company in its full form to take on chief adversary China and uphold national security in the process.

The remedies trial in Washington, D.C., follows a judge’s ruling in August that Google has held a monopoly in its core market of internet search, the most-significant antitrust ruling in the tech industry since the case against Microsoft more than 20 years ago.

The Justice Department has called for Google to divest its Chrome browser unit and open its search data to rivals. Google said in a blog post on Monday that such a move is not in the best interest of the country as the global battle for supremacy in artificial intelligence rapidly intensifies. In the first paragraph of the post, Google named China’s DeepSeek as an emerging AI competitor.

The DOJ’s proposal would “hamstring how we develop AI, and have a government-appointed committee regulate the design and development of our products,” Lee-Anne Mulholland, Google’s vice president of regulatory affairs, wrote in the post. “That would hold back American innovation at a critical juncture. We’re in a fiercely competitive global race with China for the next generation of technology leadership, and Google is at the forefront of American companies making scientific and technological breakthroughs.”

Google is one of a number of U.S. tech companies trying to fend off the Trump administration’s antirust pursuits, most of which is held over from the Biden administration. Google lost a separate antitrust case last week, when a federal judge ruled Thursday that Google held illegal monopolies in online advertising markets due to its position between ad buyers and sellers.

Meta is currently in court against the Federal Trade Commission, which has alleged that the company monopolizes the social networking market and shouldn’t have been able to acquire Instagram and WhatsApp. Amazon also faces an FTC lawsuit for allegedly maintaining an illegal monopoly. And beyond antitrust, Trump’s FTC on Monday sued Uber, accusing the ride-hailing company of deceptive billing and cancellation practices tied to its subscription service.

It’s the type of enforcement actions the tech industry was hoping to avoid when President Trump took office in January. Google, Meta, Amazon and Uber — and top executives from some — publicly donated to Trump’s inaugural fund, part of a widespread corporate effort to cozy up to the incoming administration.

For Google, the search remedies trial will determine the consequences of the guilty verdict from August. The three-week trial will end on May 9. Judge Amit Mehta is expected to make his ruling in August, at which point Google plans to file an appeal.

“At trial we will show how DOJ’s unprecedented proposals go miles beyond the Court’s decision, and would hurt America’s consumers, economy, and technological leadership,” Mulholland wrote.

Google plans to argue that Chrome provides freedom. The browser helps people access the web, and its open source code is used by other companies. One of the DOJ’s proposals is that Google open its search data, such as search queries, clicks and results to other companies.

That would “introduce not just cybersecurity and even national security risks, but also increase the cost of your devices,” Google said.

A central part of Google”s challenge is to strike a balance between being seen as essential to American innovation, but not so essential that other companies can’t compete, particularly when it comes to AI.

Google will likely tout how it’s fueled AI innovation for years and will point to the “Transformers” research paper, which provided technical architecture used in AI chatbots like OpenAI’s ChatGPT, Perplexity and Anthropic.

The DOJ has said that in search, “Google’s agreements continue to insulate Google’s monopoly.” The department plans to bring testimony from Nick Turley, ChatGPT’s head of product, and Perplexity Chief Business Officer Dmitry Shevelenko.

In a blog post on Monday, Perplexity said that “the remedy isn’t breakup,” but rather that consumers should have more choice. The company said phone makers should be able to offer their customers an assortment of search options “without fearing financial penalties or access restrictions.”

“Consumers deserve the best products, not just the ones that pay the most for placement,” Perplexity wrote. “This is the only remedy that ensures consumer choice can determine the winners.”
