Energy Storage Becomes New Growth Engine as Korean Giants Convert EV Lines

LG Energy Solution, SK On, and Samsung SDI Shift from EV to LFP Energy Storage Production

In response to slowing electric vehicle (EV) market growth, Korean battery giants including LG Energy Solution, SK On, and Samsung SDI are undertaking large-scale conversions of their U.S. EV battery production lines to manufacture lithium iron phosphate (LFP) cells for energy storage systems (ESS). For instance, LG Energy Solution's joint venture plant with GM will invest $70 million to convert its line, with mass production of LFP storage batteries scheduled for April 2026.

This collective strategic pivot signals that energy storage has overtaken EVs as the primary growth engine for the lithium battery industry. Data from GGII shows that China's energy storage lithium battery shipments reached 215 GWh in Q1 2026, a staggering 139% year-on-year increase.

Implications for B2B Buyers in the Battery Supply Chain

This means surging demand for LFP materials, ESS components, and line conversion equipment, as the industry's focus rapidly shifts toward grid-scale and commercial & industrial storage applications. B2B clients should prepare for increased procurement opportunities in these segments.

• LFP cathode and anode materials
• Energy storage system components (battery management systems, thermal management)
• Production line conversion machinery and automation solutions
