China's $10 Sodium-Ion Battery May Reshape U.S. EV Industry and Supply Chains
China's breakthrough sodium-ion battery — priced at $10/kWh (Bloomberg NEF, 2025) — is a technical marvel. It's a direct challenge to America's lithium-dependent auto industry. For context, today's cheapest lithium iron phosphate (LFP) batteries cost $75/kWh, while Tesla's 4680 cells hover near $100/kWh. At one-tenth the price, sodium-ion tech could make budget EVs like the $25,000 Tesla Model 2 financially viable overnight. American potential EV buyers hesitant because of cost will be comforted by this. When it comes.
Chinese engineers at CATL (the world's largest EV battery maker) have begun mass-producing sodium-ion cells at their new 30GWh facility in Fujian province, with plans to supply automakers like Chery and BYD by late 2025. This isn't lab hype: CATL's first-gen sodium batteries already power 250,000 urban delivery vans across China, offering 120-160Wh/kg energy density.
For cars, more needs to be done about range. But a 10,000 life cycle, to Tesla's 1500, lifespan speaks volumes. Best for grid storage and city cars, the economics are transformative. Sodium-ion production costs 70% less than lithium packs because of:
Abundant materials: Sodium carbonate costs $200/ton vs. lithium carbonate's $15,000/ton (2025 prices)
Simplified mining: Extractable from seawater or Wyoming's Green River Basin (90% of global reserves)
No cobalt/nickel: Skips conflict minerals tied to Congo's mines
Extortion free: Cannot be held to ransom by anyone on lithium supply.
Implication for US Buyers: If adopted domestically, sodium batteries could slash entry-level EV prices by $8,000–$12,000, making models like the Chevrolet Bolt 2.0 or Ford E-Transit van accessible to millions.
America's automakers are repeating history. Just as GM clung to gas-guzzling V8s during the 1970s oil crisis, today's EV strategies rely entirely on lithium—a mineral with 1,400% price volatility since 2020. If lithium supplies tighten again (e.g., Bolivia nationalizes reserves or Australia's mines strike), the fallout would be catastrophic:
EV price spikes: A $100/kWh lithium battery adds $6,500 to a 65kWh pack
Production halts: Ford's $3.5B Michigan plant depends on Chilean lithium
Geopolitical blackmail: China controls 65% of lithium refining (according to the U.S. Geological Survey)
Sodium-ion batteries offer an escape hatch. According to statements by CATL executives, the company can switch chemistries like changing shoes—lithium today, sodium tomorrow. US automakers, shackled by IRA domestic sourcing rules, lack this flexibility. That must change. And fast.
BloombergNEF predicts sodium-ion will capture 12% of the global storage market by 2030, but China's head start is alarming. While the US has its first sodium battery factory (Natron Energy's Michigan plant), its 600MWh annual output is a fraction of CATL's 30GWh.
What Washington Must Do:
Fast-track permits for sodium carbonate mining (Wyoming holds 47B tons)
Expand IRA tax credits to include sodium-ion R&D
Mandate dual-chemistry EVs by 2030
Without these steps, America risks ceding the next-gen EV race to Chinese automakers already testing 310-mile sodium-powered sedans.
The $10 battery isn't really about the chemistry. It's really a story about survival. For US buyers, sodium-ion could mean affordable EVs immune to lithium's rollercoaster. For Detroit, it's a wake-up call: innovate or watch your factories become relics, like Flint's shuttered V8 plants. The question isn't whether sodium batteries will disrupt the market, but whether America will lead, or follow, this salty revolution.

CNBC Daily Open: 'Good reports' from U.S.-China talks could push S&P 500 to new high, analysts say
Trade negotiators from the U.S. and China have met in London, and talks are expected to continue Tuesday, a source familiar with the situation told CNBC's Megan Casella. It seems that coaxing China to relax its rare earths export curbs is at the top of America's agenda, according to a CNBC interview with U.S. National Economic Council Director Kevin Hassett. If China's actions late last week — when it seemingly gave Western automakers concessions regarding those minerals — are any indication, Beijing could be willing to accede to the request. The world's second-biggest economy would demand reciprocity. On June 2, Beijing bristled at Washington's tighter grip on exports of chip design software to China. It's a good thing, then, that Washington also appears to be in a conciliatory mood. "Our expectation is that … immediately after the handshake, any export controls from the U.S. will be eased," Hassett said on CNBC's "Squawk Box." Indeed, Trump has reportedly authorized Treasury Secretary Scott Bessent's team to lift those curbs, according to The Wall Street Journal, and has described receiving "good reports" from the U.S. contingent. If the U.S.-China talks go well, there's a chance the S&P 500, only around 2% off its February high as of Tuesday morning Singapore time, could reach a new peak, noted the JPMorgan trading desk. That'd be something to cheer, of course. But it's slightly disappointing that the S&P could have continued scaling heights from February, or at least broken its closing high much earlier in the year, if not for truculent trade policy from the White House — which, as is evident from the meeting between U.S. and China, governments are still trying to undo. U.S.-China talks set to go into Day 2U.S. President Donald Trump's top trade officials met Chinese counterparts in London on Monday for talks aimed at resolving their trade dispute — particularly with regard to mineral exports. Discussions are set to continue Tuesday. Late last week, in an apparent olive branch, China seemed to offer U.S. and European auto giants something of a reprieve regarding its exports of rare earth elements. Markets inch up globallyU.S. stocks edged up Monday. The S&P 500 added 0.09%, the Dow Jones Industrial Average was mostly flat, and the Nasdaq Composite rose 0.31%. Asia-Pacific markets rose Tuesday. South Korea's Kospi index was up 0.38% at 1:30 p.m. Singapore time. Analysts from Macquarie Group say they think the country's stock market will rally and enter a bull market on the back of "expansionary fiscal policy" from the new government. A new 'Liquid Glass' look for Apple's iOSApple held its annual Worldwide Developers Conference keynote on Monday. At the event, the company announced a redesign to its iOS system called "Liquid Glass," a virtual glass look that was inspired by the Vision Pro and the most significant redesign of its operating system since 2013. Investors were underwhelmed by the announcements — which lacked developments on the AI front — and sent shares down 1.2%. UK in a 'Goldilocks' moment: Nvidia CEO "The U.K. is in a Goldilocks circumstance," Nvidia CEO Jensen Huang said Monday on a panel with British Prime Minister Keir Starmer and Investment Minister Poppy Gustafsson. "You can't do machine learning without a machine — and so the ability to build these AI supercomputers here in the U.K. will naturally attract more startups," Huang said, though he added that the country lacks homegrown AI infrastructure. [PRO] New record for S&P soon?The S&P 500 ticked higher on Monday and continues to chip away at the gap to a new record high. The broad-based index is just 2% below its record close set in February. Several events in the days ahead could prove to be the catalyst that vaults it over the top, according to the JPMorgan trading desk. China's homegrown coffee giants are brewing up a U.S. expansion Chinese beverage chains are redefining coffee culture in the country — and now they're trying to win over customers in the U.S. and beyond. Luckin Coffee, China's largest coffee chain, has expanded aggressively in China and overtaken Starbucks on the mainland, with more than twice as many outlets. After venturing into Singapore, Hong Kong and Malaysia, Luckin is set to take its biggest leap yet with plans to open a branch in lower Manhattan. "New York is probably culturally the best testing ground for an international brand to expand into, especially a Chinese one," said Bernstein senior analyst Danilo Gargiulo, citing the city's diversity and large base of young consumers. "But it's also the most saturated, one of the most competitive markets."

Canada commits billions in military spending to meet NATO target
But even if Canada is able to finally hit the 2 percent threshold, that is not likely to be enough to satisfy the United States or other NATO allies. Mark Rutte, NATO's secretary general, speaking in London on Monday, called on the alliance's members to make a 'quantum leap in our collective defense' by committing to significantly higher spending targets. Rutte wants members to commit to spending 5 percent of their gross domestic products on military and defense-related activities. Trump has called for a similar spending target. Advertisement Proposals for increased spending are likely to dominate the NATO summit meeting in The Hague this month, though Rutte has not set a timeline for his increased spending plan. Carney, speaking in Toronto, said that new geopolitical threats, advances in technology, and the fraying of Canada's alliance with the United States demanded an accelerated spending schedule. 'We stood shoulder to shoulder with the Americans throughout the Cold War and in the decades that followed, as the United States played a dominant role on the world stage,' he said. 'Today, that dominance is a thing of the past.' Advertisement 'It is time for Canada to chart its own path,' he added, 'and to assert itself on the international stage.' While Carney promised to increase spending by billions of Canadian dollars, he did not specify where the funds would come from. Government officials spoke mostly in broad terms about how the money would be used. Canada's economy is heavily dependent on exports to the United States, and Trump's tariffs have targeted key industries, including autos and steel. Some economists have warned that Canada could face a recession if the tariffs persist. Carney also said the country would no longer rely as extensively on American defense contractors to supply its armed forces, underscoring Canada's strained relations with the United States and focus on shifting away from its neighbor. The Canadian government said it would immediately add 9.3 billion Canadian dollars (about $6.8 billion) to its defense budget. That will raise total defense-related spending this year to CA$62.7 billion, slightly higher than the 2 percent NATO target. To get there, the government included CA$2.5 billion in spending related to 'defense and security' for other departments, including the Canadian coast guard, an unarmed civilian agency which is under the department of fisheries. Carney's spending pledge was welcomed by defense analysts. 'This is a long-overdue announcement,' said Margaret McCuaig-Johnston, a senior fellow at the Graduate School of Public and International Affairs at the University of Ottawa. 'This significant commitment is remarkable given how quickly they're going to have to move to make 2 percent by the end of the fiscal year.' But, she added, Carney will have to add further budget increases to fund all of the programs he is promising. Advertisement Carney laid out a long shopping list for the military, including 'new submarines, aircraft, ships, armed vehicles, and artillery.' He also said the military would add drones and sensors to monitor the seafloor in the Arctic, a vast region of the country that is becoming a source of competition among global powers such as Russia and China. But Canadian officials said that this year most of the spending would go toward things like increasing the pay and the benefits of armed forces members to help ease a severe recruitment crisis, and repairing broken equipment. Carney also said that money would be directed toward much-needed improvements, noting that three of the Royal Canadian Navy's four diesel submarines were not seaworthy. 'We will repair and maintain our ships, our aircraft, and infrastructure that for too long we allowed to rust and deteriorate,' the prime minister said. Other spending will focus on artificial intelligence and computer systems, as well as ammunition production within the country. Carney also said that Canada would look to buy more goods domestically or from allies other than the United States to equip its military. 'We should no longer send three-quarters of our defense capital spending to America,' he said. Carney said Monday that details about how the country's military needs would be financed would be revealed when a budget was released in the fall. 'Our fundamental goal in all of this is to protect Canadians,' he told reporters, 'not to satisfy NATO accountants.' This article originally appeared in

China's tech firms block AI access during high-stakes college entrance exams
In China, one exam can decide your future, and this year, students weren't allowed any help from AI. As millions of high school seniors began sitting for China's notoriously grueling "gaokao" college entrance exam from Saturday, the country's biggest tech firms quietly pulled the plug on their AI tools. Apps from Tencent, ByteDance, and Moonshot AI disabled features like photo recognition and real-time question answering, a move aimed at preventing students from using chatbots to cheat during the high-stakes national exam. Last month, China's education ministry warned students not to rely on AI-generated answers for assignments or tests, even while promoting AI education from a young age. This year, about 13.4 million students are taking the "gaokao," which runs from Saturday to Tuesday, according to local media. Unlike the US college admissions process, which often considers essays, extracurriculars, various standardized exams, and school records, China's system leans almost entirely on this one test. For many students, especially those from rural or low-income backgrounds, the "gaokao" is a once-a-year shot at social mobility. That kind of pressure has fueled an arms race in test prep, from private tuition centers to after-school cram schools. But over the weekend and into this week, AI was off the table. Chinese chatbots go dark Screenshots posted by users on the Chinese app Rednote showed that popular AI chatbots like Tencent's YuanBao, ByteDance's Doubao, and Moonshot AI's Kimi had disabled exam-relevant features during testing hours. In one post on Sunday, a user who goes by "DKK" attempted to upload what appeared to be a test paper to Doubao. The chatbot immediately shut it down: "The image content is not compliant and the upload failed." In another screenshot posted on Monday, user "Gemini0612" asked Doubao for help with a question. The chatbot responded with a notice: "We are very sorry. In order to ensure the fairness of the college entrance examination, Doubao's Q&A function will be temporarily closed during the examination period and will be restored after the examination at 6.45 p.m. this afternoon. Thank you for your understanding and support, and wish all candidates good luck in the college entrance examination." Tencent's YuanBao replied with a similar message in another screenshot posted Monday: "Dear users, to ensure fairness in the college entrance examination, this function is not available during the college entrance examination period. Tencent's Yuanbao wishes all candidates success in the exam." Tencent's chatbot offers users a choice between its in-house Hunyuan model and DeepSeek's R1. The Shenzhen-based tech giant has integrated both models across its vast ecosystem, including WeChat, China's biggest social media app used by nearly 1.4 billion people. Moonshot AI's chatbot Kimi also locked down its photo-recognition and question-answering functions. In a Rednote post on Sunday, a user who said he is a college student uploaded a photo of a question and asked Kimi for help. The chatbot responded with another canned message about ensuring fairness during the college entrance examination period. The user pushed back: "I am not a college entrance examination candidate. The college entrance examination does not test this." But Kimi didn't budge. Tencent, ByteDance, and Moonshot AI did not respond to a request for comment from Business Insider. China wants students to learn AI — just not use it to cheat China is all in on AI education. In China's capital, Beijing, AI education is compulsory for students, including elementary schoolers. Starting this fall, schools in the city must provide at least eight hours of AI instruction per academic year, the Beijing Municipal Education Commission said in March. While the country is racing to build an AI-literate generation, regulators are also drawing a hard line, saying AI is for learning, not for shortcuts. By pulling the plug during the "gaokao," tech firms reinforced the message: AI has no place in the exam hall.
