South Korean battery manufacturer SK On’s US production facilities will supply NeoVolta Power with 9GWh of lithium iron phosphate (LFP) pouch cells under a five-year deal.

Two South Korean-headquartered companies, LG Energy Solution and DeltaX are establishing battery cell factories in the US.

L-H Battery Company commenced lithium-ion (Li-ion) cell production at its Jeffersonville, Ohio, US plant this month, for automotive and stationary power applications.

LG ES posted a quarterly loss in Q1 2026 financial results this morning, partly due to investments in energy storage system (ESS) cell manufacturing.

The project represents a US$128.6 million investment and is scheduled to begin construction this year, with commercial operations commencing in December 2026.

LG Energy Solution has entered into a US$4.3 billion supply agreement with Tesla, announced by the US government, while simultaneously upgrading its EV battery plant with GM for ESS cells.

On 4 September, US Immigration and Customs Enforcement (ICE), along with multiple other law enforcement organisations, raided Hyundai Motor and LG Energy Solution’s electric vehicle (EV) battery cell plant in Ellabell, Georgia, US.

LG Energy Solution and Stellantis’ joint venture (JV), NextStar Energy, Canada’s first large-scale lithium-ion (Li-ion) battery manufacturing plant, is expanding to produce energy storage system (ESS) batteries.

Samsung SDI is ramping up its manufacturing of energy storage batteries in the US to 30GWh by the end of 2026, while EV demand remains sluggish.

Tesla could be “hedging its bets” on battery cell supply, if a deal announced by LG Energy Solution really is with the US EV and BESS company.
