Ideas
K-battery wins as ESS demand explodes.
The U.S. is explicitly blocking Chinese batteries, so North American ESS demand is exploding and Korean battery makers are effectively the main non-China supply; this year and next, North American ESS battery demand will exceed EV battery demand, and ESS is shifting toward high-priced, high-spec AI data center and grid applications, which should drive Korean battery cell makers to higher utilization and share gains.
K-battery wins as ESS demand explodes.
Korea is expected to pass a 10-year production tax credit for domestic battery production by year-end, possibly with third-party credit transfers; with the first renewable energy basic plan requiring about 10GW of renewable build per year and about 20GW of ESS, plus about 18GW of ESS for AI data centers, domestic demand of about 38GW exceeds full domestic capacity, so domestic cell production at Seosan, Ulsan, and Ochang should receive a large tax incentive and run at full capacity.
POSCO Future M LFP demand stays tight.
POSCO Future M converted an existing line to LFP and secured a 190,000-ton LFP cathode contract worth about 3 trillion won over six years, implying roughly 500 billion won of annual revenue; FEOC rules require cell makers to source around 80 percent non-China cathode, so LFP cathode supply should stay tight and benefit POSCO Future M and L&F.
Lithium bottomed; expect upward price trend.
Lithium prices fell to around $22/kg after supply bottlenecks eased in June, but Chinese lithium carbonate inventory days have fallen from about 40 to 19 days, global lithium demand is exploding, and UBS and the IEA see a third lithium supercycle with demand tripling by 2030; he expects lithium to bottom near $22 and trend upward in the second half.
EU rules shift battery sourcing to Korea.
The EU Industrial Acceleration Act is effectively a Made-in-EU policy that will force automakers to cut Chinese battery procurement to 30 percent or less from current levels of 65 to 88 percent; European local battery plants are not yet viable, while Korean battery makers already operate in Hungary and Poland, so they should see European capacity utilization rise sharply as Chinese volumes are reallocated to Korean suppliers, reinforced by battery passport, carbon footprint, and critical raw material rules.
Battery materials and equipment follow shortage.
If a shortage develops, battery cells should tighten first, then the shortage should transfer to materials, and subsequent expansion should lift equipment suppliers; Korean battery makers have mostly expanded overseas, but domestic expansion will become inevitable as renewable targets are built, so battery materials and equipment names should get trickle-down benefits.
Samsung SDI has funding, prismatic edge.
Samsung SDI has financial strength supported by its display business and a differentiated prismatic form factor advantage; although its North American capacity is smaller than LG Energy Solution's, its balance sheet and prismatic technology give it a distinct competitive edge among Korean cell makers.
