As of September 29, 2026, Samsung SDI is making its first appearance at DCWA 2026 (Data Center World Asia), which opened in Singapore today, with a battery lineup built for AI data centers. The standout is its cylindrical LFP (lithium iron phosphate) battery, which the public is seeing in physical form for the first time.

Key points

This is Samsung SDI's first booth at DCWA, an event with more than 600 companies on its roster.
The booth is split into four zones: UPS, BBU, SBB and cells.
The UPS product at the center of the booth was billed as passing every item in a large-scale fire test (LSFT) run by UL Solutions.
A prismatic LFP battery destined for the SBB 2.0 all-in-one energy storage system is also on display.

Samsung SDI says it is using DCWA 2026, a data center industry show in Singapore, to roll out battery solutions for AI data centers. The show covers the whole industry, from designing and building data centers to running and managing them, and ranks among the largest in Asia. It's Samsung SDI's first time showing up.

The cylindrical LFP battery is the centerpiece. According to the company, in-house structural technology boosts power output and capacity while also improving safety. Samsung SDI also brought a prismatic battery that uses LFP chemistry. That one is slated for SBB 2.0, an all-in-one energy storage system (ESS).

Safety was the message running through the whole booth. The UPS (uninterruptible power supply) solution in the middle of the floor reportedly passed every item in the LSFT run by UL Solutions, a test that checks for battery explosion and heat-spread risks. The BBU (battery backup unit) zone features a ternary-chemistry 21700 cylindrical cell with a vent structure at the bottom, along with a cylindrical product designed for emergency power at AI data centers.

During the show, Samsung SDI plans to brief global customers on its technology development and present its data center battery solutions at a local technical conference. Some reports read the move as an effort to build a new revenue base in power-hungry, fire-sensitive Big Tech data centers while electric vehicle demand stays soft. A company representative said Samsung SDI will keep leading with performance and safety and offer products tailored to each customer's needs.

In Korea right nowKorean outlets are framing Samsung SDI's appearance as an attempt to widen its playing field from EVs, where the market has stalled, to AI data centers. Two things are drawing attention: the fire-safety test results placed front and center at the booth, and a LFP lineup that now covers both cylindrical and prismatic formats.
