Samsung SDI, one of South Korea’s three major battery makers, posted a steep operating loss in 2025 as the global market for electric vehicle batteries slumped. The company reported an operating loss of more than KRW1.7 trillion (US$1.17 billion) for the year. However, it is betting that a shift in strategy—anchored by local production of lithium iron phosphate (LFP) batteries in the United States and an expansion of its energy storage systems business—will return it to profitability in 2026.
