Posco Future M signs $4.5bn Samsung SDI LFP deal
Posco Future M signed a $4.5B deal with Samsung SDI to supply LFP cathode materials from 2027 to 2032, more than doubling a prior agreement. The company is converting production lines and building a new plant to meet demand. Korean battery firms are expanding in North America due to US restrictions on Chinese suppliers, which require increasing shares of non-Chinese materials for tax credits.
How this was made

The 30-second read
Why it matters
The new multi-year contract plus line conversion and a dedicated plant indicate tangible capacity and procurement commitments that can shift expectations for LFP cathode supply tightness and downstream battery/energy storage build plans.
Market read
A large, multi-year LFP cathode supply deal and capacity conversion signals procurement and production visibility into 2027-2032, relevant for battery materials and energy storage supply chains.
What to watch
The article does not specify pricing, pass-through terms, or customer qualification timelines, which can materially affect realized margins and contract profitability.
Background
Posco Future M is expanding LFP cathode active materials capacity and has multiple supply agreements, including a prior SK On deal and the new Samsung SDI agreement.
Market effects
Reinforces the industry shift toward LFP cathode materials and capacity buildouts, with US tax-credit sourcing rules favoring non-prohibited supply chains.
Highlights Korean cathode makers expanding LFP output and North America energy storage exposure amid EV battery slowdown.
Points to China’s dominant LFP cathode and cell production, while US rules increase the importance of qualifying supply origins.
Counterpoint
LFP is less favored for premium EV range needs, so demand growth may be concentrated in energy storage rather than broad EV adoption.
