Korea Bets 8.4 Trillion Won on Sodium, Solid-State Batteries

Korea's 8.4 trillion won investment in sodium-ion and solid-state batteries is a direct response to China's pricing power. Chinese firms now hold 61% of Europe's EV battery market, up from 42% in 2023. Korean makers saw their share drop to 35% from 55% in the same period. This shift is not about new technology; it is about market share. Korea must compete on cost in entry-level EVs and energy storage, where LFP batteries are 40% cheaper than NCM packs.

The strategy to diversify beyond NCM cells is necessary. Korea's secondary battery exports fell 27.6% in three years, to $7.23 billion last year from $9.98 billion in 2022. This shows a clear loss of competitiveness in core markets. Targeting 220 Wh/kg for sodium-ion by 2030 and 400 Wh/kg for solid-state by 2028 addresses both ends of the market. This dual approach could help Korean firms regain ground in specific segments.

The real test for Korea will be commercializing solid-state batteries by 2030. This technology targets high-performance EVs, robots, and urban air mobility. If successful, it offers a premium segment where China has less established dominance. Joint development among companies like LG Energy Solution and Samsung SDI is crucial to avoid duplicate investment and accelerate market entry.
