Posco Future M advances LMR cathodes to rival China's LFP dominance
Posco Future M announced Tuesday that it has completed the development of lithium manganese-rich (LMR) cathode materials for electric vehicle batteries, which it hopes will be a competitive alternative to Chinese products.
The company recently received approval from its primary clients — mainly battery manufacturers — to prepare for mass production, following inspections of equipment operation, safety, and environmental standards in the LMR manufacturing process. It aims to secure mass production capabilities within this year.
While the exact production location remains undisclosed, Posco Future M emphasized that it will utilize its existing nickel, cobalt and manganese (NCM) cathode production lines to ensure a timely supply for clients. The company currently operates three manufacturing bases in Gwangyang, South Jeolla Province, Pohang, North Gyeongsang Province, and Sejong.
In collaboration with the research institute of its parent company, Posco Holdings, Posco Future M has steadily improved the energy density, charge-discharge performance, and stability of LMR cathodes, achieving successful pilot production last year.
LMR cathodes are considered a potential game-changer for batteries used in entry-level and standard EVs. They are attracting attention from global automakers seeking alternatives to China's lithium iron phosphate batteries as carmakers face growing pressure to decouple their supply chains from China in order to meet US regulatory requirements.
Posco Future M highlighted that LMR batteries offer competitive pricing compared to LFP batteries, while delivering 33 percent higher energy density. This cost efficiency is made possible by significantly reducing the use of expensive materials like cobalt and nickel, and instead increasing the proportion of more affordable manganese.
The company also plans to expand its LMR product portfolio by developing next-generation cathode materials with even higher energy capacity, with the goal of serving not only entry-level EVs but also premium and large-size EV markets.
'Although LMR cathode materials have long been recognized for their potential, commercialization was hindered by challenges related to lifespan,' said Hong Hyung-jun, director of the Posco Future M Technology Research Center. 'However, significant R&D progress has been made. We are now ready to launch products that combine affordability with high energy density, working closely with our trusted partners.'
Meanwhile, General Motors has announced plans to launch EVs equipped with LMR batteries by 2028. Ford Motor Company is also targeting LMR battery commercialization before 2030 and is currently conducting pilot production of advanced LMR cells.

Trump speaks with Xi amid stalled talks between the US and China over tariffs
WASHINGTON -- President Donald Trump and his Chinese counterpart, Xi Jinping, have spoken amid stalled negotiations between both countries over tariffs that have roiled global trade. The discussion on Thursday followed Trump suggesting it was tough to reach a deal with Xi. 'I like President XI of China, always have, and always will, but he is VERY TOUGH, AND EXTREMELY HARD TO MAKE A DEAL WITH!!!,' Trump posted Wednesday on his social media site. Trade negotiations between the United States and China stalled shortly after a May 12 agreement between both countries to reduce their tariff rates in order to have talks. Behind the gridlock has been the continued competition for an economic edge.

Is foreign appetite for housing a threat to Korea?
Residential properties owned by foreign nationals surpass 100,000 in 2024 Foreign nationals are increasingly entering the housing market, and their growing presence is beginning to raise questions about the future of housing access, investment behavior and regulatory oversight. Over the past three years, the number of homes owned by foreign buyers has steadily increased, rising by 4 to 6 percent every six months. Recently, the trend reached a new milestone. As of late December, foreign nationals owned more than 100,000 housing units in South Korea — the first time the figure has crossed that threshold since the government began tracking it in 2022, according to data from the Ministry of Land, Infrastructure and Transport. Though these properties comprise only about 0.5 percent of South Korea's roughly 20 million housing units, the uptick has prompted questions about whether some purchases are being made for investment purposes rather than for residential use. Regulatory gaps for non-residents have also been a point of discussion. The available data provides a broad snapshot but leaves out key details. It does not distinguish between buyers who reside in Korea and those who may be investing from overseas. Nor does it track the motivations behind purchases — whether for long-term living, rental income or speculation. Foreign residents who have stayed in Korea for more than 90 days now number over 2 million, suggesting that, proportionally, foreign ownership remains relatively modest. Still, patterns within the data reveal some concentration. Chinese nationals accounted for the largest share of foreign-owned homes, followed by US and Canadian citizens. The capital region is by far the most popular area for foreign buyers. Nearly three-quarters of all foreign-owned homes are located in the greater Seoul area, with more than 23,000 properties situated within the city itself. Most foreign homeowners — about 93 percent — own just one home. However, a small number hold multiple properties, including 461 individuals who own five or more units, which some see as a potential sign of investment activity. As the trend continues, policymakers and analysts are watching closely, not because the numbers are overwhelming, but because of the broader implications — from housing availability to the effectiveness of existing oversight mechanisms. Dodging the rulebook Some argue that foreign nationals may have an easier time acquiring real estate in South Korea by securing financing from lenders in their home countries, a strategy that could allow them to bypass Korea's stringent loan regulations. Certified transcripts — documents required when purchasing land or housing in Korea — show instances of foreign buyers acquiring high-end properties at record-high prices, often paid in full with cash. 'Foreigners take out loans from overseas banks to purchase housing here, distorting the local real estate market,' said Kwon Dae-jung, a professor of real estate at Sogang University's Graduate School. Others, however, argue that the practice is likely limited in scope, as obtaining loans for overseas property purchases can be difficult. 'Securing a loan in a foreign country to buy residential property in Korea would not be easy, unless the buyer is extremely wealthy,' said an official at a local real estate investment firm. 'Even in commercial real estate, offshore investors usually prefer to finance through local banks. For residential housing, cross-border financing tends to be even more difficult.' Foreign nationals are subject to the same borrowing limits at Korean banks as local citizens, including regulations based on loan-to-value and debt-to-income ratios. Still, completely closing off regulatory loopholes remains a challenge. While Korea imposes heavier taxes on multi-homeowners, enforcing these rules among foreign nationals can be challenging, particularly in identifying household members living abroad. Calls for tightened grip Regulatory efforts to manage demand from foreign homebuyers in Korea continue to gain traction, with some measures targeting Chinese nationals — the largest group of foreign property owners in the country. In May, Rep. Ko Dong-jin of the ruling People Power Party proposed a bill that would introduce a permit system for foreign nationals seeking to purchase property in the greater Seoul area. Citing the principle of reciprocity, Ko argued that Chinese nationals' access to Korean real estate should be limited, pointing out that South Koreans face similar restrictions when attempting to purchase property in China. Ko's proposal is part of a broader, bipartisan push by lawmakers in recent years to tighten regulations on foreign ownership. Other initiatives have included calls for higher acquisition taxes and stricter property-related rules for non-Korean buyers. However, none of these measures have passed the legislative threshold. Legal experts argue that regulating property purchases by nationality could violate the constitutional principle of reciprocity. Despite the legal challenges, authorities are continuing their efforts to monitor and respond to growing concerns. On Monday, Seoul Mayor Oh Se-hoon ordered a comprehensive investigation into real estate transactions involving foreign nationals. He called for a full review of foreign ownership patterns and proposed additional safeguards to prevent potential market distortions or what he described as 'reverse discrimination' against Korean citizens. Although there is currently no conclusive evidence that foreign homeownership is driving instability in the housing market, officials remain wary. 'The government has to figure out a way to strengthen measures to track down foreign purchases of local residential properties. Otherwise, the rising foreign demand will drive up further market distortion," Kwon said.

China's rare earth export curbs hit auto industry
BERLIN/FRANKFURT, Germany (Reuters) — Some European auto parts plants have suspended output and Mercedes-Benz is considering ways to protect against shortages of rare earths, as concerns about the damage from China's restrictions on critical mineral exports deepen across the globe. China's decision in April to suspend exports of a wide range of rare earths and related magnets has upended the supply chains central to automakers, aerospace manufacturers, semiconductor companies and military contractors around the world. China's dominance of the critical mineral industry, key to the green energy transition, is increasingly viewed as a key point of leverage for Beijing in its trade war with US President Donald Trump. China produces around 90 percent of the world's rare earths, and auto industry representatives have warned of increasing threats to production due to their dependency on it for those parts. "It just puts stress on a system that's highly organized with parts being ordered many weeks in advance," said Sherry House, Ford's finance chief, at an investor conference Wednesday. She said China's export controls add administrative layers that are sometimes smooth, and sometimes not. "We're managing it. It continues to be an issue, and we continue to work the issues." EU Trade Commissioner Maros Sefcovic said Wednesday that he and his Chinese counterpart had agreed to clarify the rare earth situation as quickly as possible. "We must reduce our dependencies on all countries, particularly on a number of countries like China, on which we are more than 100 percent dependent," said EU Commissioner for Industrial Strategy Stephane Sejourne. "The export (curbs) increase our will to diversify," he said as Brussels identified 13 new projects outside the bloc aimed at increasing supplies of metals and minerals essential. Europe's auto supplier association CLEPA said several production lines have shut down after running out of supplies, the latest to warn about the growing threat to manufacturing due to the controls. Of the hundreds of requests for export licenses made by auto suppliers since early April, only a quarter have been granted so far, CLEPA added, with some requests rejected on what the association described as "highly procedural grounds." It did not identify the companies but warned of further outages. While China's announcement in April coincided with a broader package of retaliation against Washington's tariffs, the measures apply globally and are causing worry among business executives around the world. Earlier Wednesday, Mercedes-Benz production chief Joerg Burzer said he was talking to top suppliers about building "buffers" such as stockpiles to protect against potential threats to supply. Mercedes was currently not affected by the shortage. BMW said that part of its supplier network was disrupted, but its own plants were running as normal. German and US automakers have complained that the restrictions imposed by China threaten production, following a similar grievance from an Indian EV maker last week. Mathias Miedreich, board member for electrified propulsion at German automotive supplier ZF Friedrichshafen, said the company has largely been able to get needed permits from China. In a media briefing Tuesday, he said he worries though that the situation eventually could resemble the computer-chip shortage during the COVID-19 pandemic, which wiped out millions of vehicles from automakers' production plans. Many are lobbying their governments to find a quick solution but some companies only have enough supplies to last a few weeks or months, Wolfgang Weber, CEO of Germany's electrical and digital industry association ZVEI, said in an emailed statement. Swedish Autoliv, the world's biggest maker of air bags and seat belts, said its operations are not affected, but CEO Mikael Bratt said he has set up a task force to manage the situation. There are few alternatives to China. Automakers from General Motors to BMW and major suppliers like ZF and BorgWarner are researching or have developed motors with low- to zero rare earth content in a bid to cut their reliance on China, but few have managed to scale production to bring down costs. BMW has deployed a magnet-free electric motor for its latest generation of electric cars, but still requires rare earths for smaller motors powering components like windshield wipers or car window rollers. "There is no solution for the next three years except to come to an agreement with China," said Andreas Kroll, managing director of Noble Elements, a rare earths importer for medium-sized companies and startups without their own inventories. "China controls practically 99.8 percent of global production of heavy rare earths. Other countries can only produce these in minimal quantities, virtually on a laboratory scale."
