Korea bets big on sodium and solid-state tech to reclaim battery dominance

At a high-level industry summit held Tuesday at the Korea Chamber of Commerce and Industry in Seoul, officials from the Ministry of Trade, Industry and Energy met with executives from top battery giants, including LG Energy Solution, Samsung SDI and SK On. Together, they unveiled the nation’s official Battery Technology Roadmap, outlining a massive public-private push focused on next-generation chemistries and dramatic cost reductions. The strategic shift marks a clear departure from Korea’s long-standing reliance on high-nickel NCM (nickel-cobalt-manganese) cells. While premium NCM batteries established Korean manufacturers as global leaders in high-performance electric vehicles, Chinese rivals have rapidly gained market share by flooding global supply chains with low-cost lithium iron phosphate alternatives. To counter this squeeze, Korea is pivoting toward a "select and concentrate" strate
