How Does Samsung SDI Co Company Work?

How is Samsung SDI Co accelerating the green energy shift?

In early 2025 Samsung SDI began mass producing 46-diameter cylindrical batteries, reinforcing its role in EVs, ESS and electronics after exceeding 23 trillion KRW in revenue. The firm focuses on high energy density, safety and advanced materials under the PRiMX brand.

Samsung SDI combines chemical R&D, precision cell manufacturing and strategic partnerships to serve OEMs and utility-scale projects, aligning investments with regional policies like the IRA.

Samsung SDI's core operations center on two divisions: Energy Solutions, producing EV and ESS batteries, and Electronic Materials, supplying advanced cathodes and separators. The company combines high-nickel NCA technology with a globally distributed manufacturing footprint to deliver technical superiority and localized supply.

Energy Solutions

Focuses on large-format EV batteries, ESS for grids, and small cells for IT and tools, driving most revenue through automotive partnerships and grid projects.

Electronic Materials

Produces cathode active materials and separators supporting in-house cells and third-party manufacturers, enhancing vertical integration and margin control.

Manufacturing Footprint

Major hubs in Ulsan, Xi'an, Göd and expanding US plants enable regional supply, with just-in-time delivery and reduced logistics risk for OEM customers.

Supply Chain Strategy

Vertical integration, long-term mineral off-takes and recycling investments aim to stabilize input costs and secure critical raw materials.

Operational highlights and value drivers emphasize technology, scale and partnerships that define the Samsung SDI business model and how Samsung SDI operates in the EV battery market and beyond.

Technical Edge & 2025 Milestones

By 2025 Samsung SDI scaled Gen 6 P6 production with a high-nickel NCA chemistry, enhancing energy density and reducing unit costs through manufacturing improvements.

• Gen 6 P6 contains 91 percent nickel, delivering roughly a 10 percent energy density increase versus prior cells
• StarPlus Energy JV with Stellantis launched its first North American plant in 2025 to support local EV demand
• Global capacity expansion targets and regional plants aim to shorten lead times and improve integration with OEMs
• Recycling and mineral off-take agreements reduce exposure to raw material price volatility and support circular supply

Samsung SDI's revenue model is led by automotive-grade lithium-ion battery sales, complemented by electronic materials that stabilize margins. The company balances high-volume, contract-driven EV battery revenues with high-margin chemical products to sustain R&D and capital investment.

Automotive Battery Sales

The core of the Samsung SDI business model is automotive batteries, which represent roughly 75–80% of consolidated revenue in recent years.

Energy Solutions Division

The Energy Solutions division posted annual revenues exceeding 19 trillion KRW in the 2024–2025 period, driven by EV and ESS sales.

Long-term OEM Contracts

Revenue is secured via long-term supply contracts with premium OEMs such as BMW, Audi, Volvo, and Stellantis, reducing demand volatility.

Price-indexing Clauses

Contracts often include price-indexing to pass through lithium, nickel, and cobalt cost fluctuations, protecting margins amid raw-material volatility.

Energy Storage Systems (ESS)

ESS and SBB (Samsung Battery Box) offerings are high-growth monetization vectors as utilities and commercial customers adopt renewables and storage solutions.

Electronic Materials

The Electronic Materials division provides 20–25% of revenue from high-margin products like polarizer films, photoresists, and EMC used in semiconductors and displays.

Samsung SDI operates a dual-stream monetization strategy that pairs high-volume automotive battery contracts with stable, high-margin electronic materials sales, enabling continued R&D reinvestment of around 5–7% of revenue and strengthening the Samsung SDI company structure.

Key Revenue Mechanics

Revenue and profitability depend on contract design, product mix, and vertical synergies within the broader Samsung group.

• Long-term OEM supply contracts with price-indexing to mitigate commodity risk
• ESS/SBB sales capturing grid-scale and commercial storage demand
• Electronic materials provide margin stability through proprietary formulations
• R&D reinvestment of 5–7% of revenue to support next-gen battery tech
