Samsung SDI Debuts Cylindrical LFP Battery for AI Data Centers

Samsung SDI showcased its latest battery technology at Data Center World Asia (DCWA) 2026, the premier data center exhibition in Asia. The company introduced a cylindrical lithium iron phosphate (LFP) battery, designed to enhance safety and performance for AI data centers. At the demonstration, Samsung SDI positioned four key areas: uninterruptible power supply (UPS), battery backup units (BBU), the Samsung Battery Box (SBB), and cell lines to display its technical strengths.

The UPS section featured the world's first battery to pass a large-scale indoor fire test, conducted by UL Solutions, confirming its high safety standards. The BBU area displayed a high-capacity ternary battery, with a notable focus on emergency power supply for AI data centers. The SBB zone introduced a prismatic LFP battery, which would integrate into the company's "SBB 2.0" all-in-one energy storage solution, blending LFP materials with Samsung SDI's unique prismatic design for better performance and safety.

Samsung SDI also participated in a technical conference, showcasing the intricate details of its battery innovations and engaging with global customers. The company's president expressed confidence in unveiling more differentiated solutions tailored to the evolving needs of data center customers, backed by improved financial performance.

In the second quarter of 2026, Samsung SDI reported a revenue of 3.7688 trillion won ($2.79 billion) and an operating profit of 203.8 billion won, marking their first profitable quarter in seven years. The growth in ESS demand, driven by expanding AI data center investments and a rebound in the European electric vehicle market, is anticipated to bolster the company's technological advancements.
