Summary

Eugene Investment & Securities research director Han Byung-hwa argues that secondary batteries have bottomed and that the recent semiconductor-driven selloff creates an accumulation window for Korean battery names. He points to ESS/AI data center demand, Samsung SDI's utilization recovery to 73%, and next platforms sodium/LMR as key supports, while also seeing long-term battery demand expanding into drones, robots, electric aircraft, and ships. He expects US and European efforts to constrain Chinese battery makers to benefit Korean companies.

  • Lithium carbonate rebounded and stabilized near 150,000 yuan, which he views as healthier than another price spike.
  • ESS demand from AI data centers is boosting LG Energy Solution and Samsung SDI revenues by 20-30%.
  • Samsung SDI's first-half utilization rate rose to 73% from around 50%, signaling a bottom and improvement.
  • Korean battery stocks should be accumulated before the expected Q4-to-next-year earnings inflection.
  • Sodium and LMR battery material/component suppliers are highlighted as the next opportunity after LFP.
  • Battery applications are expanding to humanoid robots, drones, electric aircraft, and ships, supporting long-term high-density battery demand.
  • US and Europe are constraining Chinese battery/EV makers, which should create replacement demand for Korean battery companies.
Ideas
Han Byung-hwa Director 0:18
Buy Korean battery stocks now.
Korean battery stocks are at a bottom/turnaround and the recent vertical pullback from semiconductor-driven supply disruption left no room for earnings improvement to be priced. Earnings are starting to improve, Samsung SDI already swung to profit, and the sector should show clearer inflection from Q4 this year into next year. Because share prices tend to lead fundamentals by about six months, investors should accumulate battery names whose earnings are improving now.

ESS demand boosts K-battery makers.
China's dominance is already priced into Korean battery valuations. The US is successfully blocking Chinese batteries/EVs, and Europe is finalizing its Industrial Acceleration Act because Chinese EVs are damaging its auto industry. With Europe lacking domestic battery champions, Korean companies are the natural replacement to fill the gap, supporting a positive K-battery view.
Han Byung-hwa Director 2:11
ESS demand boosts K-battery makers.
ESS demand is becoming the near-term driver for Korean battery makers because AI data centers require lithium-ion energy storage to stabilize highly volatile power loads. LG Energy Solution and Samsung SDI are reporting ESS revenue growth of 20-30%, and US ESS capacity expansion and LFP conversion are improving conditions into next year even while EV demand remains weak.
Han Byung-hwa Director 10:35
Buy sodium/LMR battery suppliers.
Because LFP is China-dominated and Korea cannot win on cost, the next Korean battery opportunity is sodium and LMR platforms where the market is not yet formed. LG Energy Solution and Samsung SDI are already pushing sodium mass-production investment, with test lines likely next year, and Han recommends investing in related material and component suppliers.
Han Byung-hwa Director 14:31
Battery applications expand beyond EVs.
Battery applications are broadening rapidly beyond EVs into humanoid robots, drones, electric aircraft, and ships. High-density ternary batteries are improving enough to meet these new demands, and solid-state should follow. In a 10-20 year view battery penetration will be far larger, so current moves in battery stocks are small relative to the long trend.
