Samsung SDI targets AI data centers with first cylindrical LFP battery unveiling

Samsung SDI is expanding its battery lineup targeting the AI data center market, showcasing solutions spanning uninterruptible power supplies, battery backup units and energy storage systems under one roof.

The company participated in Data Center World Asia 2026, which opened Tuesday in Singapore, unveiling battery products and technologies designed for AI data centers. The event, which covers data center design, construction and operations management, drew about 600 companies this year.

Samsung SDI organized its exhibition space into four zones: UPS, BBU, SBB (Samsung Battery Box) and battery cells.

The standout product was a cylindrical lithium iron phosphate (LFP) battery making its public debut at the show. Samsung SDI applied proprietary structural technology to boost both output and capacity while strengthening safety.

BBU devices supply power to servers during emergencies such as outages at data centers. Samsung SDI also displayed a high-output, high-capacity 21700-format cylindrical nickel-manganese-cobalt battery featuring a bottom-vent structure.

In the UPS segment, the company highlighted fire safety. Its UPS solution met the evaluation criteria in a large-scale indoor fire safety test conducted by global safety certification body UL Solutions. The test assesses the risk of explosion and thermal runaway spreading to adjacent batteries when a fire breaks out.

Samsung SDI also exhibited a prismatic LFP battery used in its ESS product "SBB 2.0," which applies LFP chemistry to a conventional prismatic cell structure. The product targets not only data centers but also the large-scale ESS market.

"We will continue to present differentiated solutions capable of meeting the diverse needs of data center customers, backed by battery technology with improved performance and safety," a Samsung SDI official said.
