At RE+ 2025, Company showcases high-capacity SAMSUNG Battery Box 1.7 and LFP-applied 2.0
The exhibition includes battery cells for UPS solutions optimized for AI data centers, SAMSUNG SDI’s prismatic battery technology
“SAMSUNG SDI aims to strengthen competitiveness in the U.S. market with leading prismatic battery technology and robust local production capabilities”
SEOUL, Korea – September 9, 2025 – SAMSUNG SDI today announced that it debuted next-generation energy storage system (ESS) products at Renewable Energy Plus (RE+) 2025, the biggest energy industry trade show in the United States, which kicked off on September 9 for a three-day run.

With the proclamation of “All-American, Proven & Ready,” the South Korean battery maker attracted industry-wide attention as it emphasized local production capabilities and differentiated ESS technologies aimed at advancing the U.S. ESS market.
At RE+ 2025, held at the Venetian Expo & Caesars Forum in Las Vegas, SAMSUNG SDI unveiled an exhibition booth organized into five dedicated zones—SAMSUNG Battery Box (SBB), uninterruptible power supply (UPS) solutions, prismatic battery, U.S. production, and award-winning products—highlighting its latest innovations and technologies.
At the heart of the exhibition is the SBB zone, showcasing the next-generation SBB 1.7 and SBB 2.0. Making their debut at this event, both products are scheduled for U.S. production beginning next year.
SBB is an all-in-one solution that houses battery cells, modules, and racks inside a 20-foot container, allowing immediate connection to the power grid. Recognized for its ease of use, high performance, and safety, the SBB was honored with the CES Innovation Award earlier this year.
The 6.14MWh SBB 1.7, equipped with high-nickel NCA cells, delivers about 17% higher energy density than the previous SBB 1.5, enabling greater efficiency and performance.
The SBB 2.0, powered by lithium iron phosphate (LFP) cells for the first time, features SAMSUNG SDI’s proprietary prismatic form factor and differentiated material, electrode technologies, which help overcome low energy density of LFP cells and maximize advantages such as safety and low price.
Both models integrate Enhanced Direct Injection (EDI) technology, delivering enhanced safety and reliability. They are also designed with the company’s AI-based predictive maintenance and durability prediction algorithms.
SAMSUNG SDI plans to roll out the new SBB products through local production to respond to the growing U.S. demand, despite the tightening conditions for local production and rising supply chain risks stemming from U.S. tariff policies.

At the UPS zone, the company unveiled a new uninterruptible power supply (UPS) solution U8A1 that won the Smarter E Europe 2025 Innovation Award at Europe’s largest energy exhibition held in Munich last May.
With a 33% increase in space efficiency over previous models, the U8A1—equipped with high-power, high-energy density cells—allows data center customers to respond to power cuts more quickly and reliably, using fewer cells.
Unlike conventional UPS cells designed for emergency backup, SAMSUNG SDI’s UPS solution helps stabilize power quality during peak demand periods. The UPS cells utilize lithium manganese oxide chemistry, delivering both high-power performance and enhanced safety. They have also passed the U.S. fire safety standard test (UL9540A).
At the prismatic battery zone, SAMSUNG SDI is once again showcasing its accumulated expertise in prismatic battery technology.
SAMSUNG SDI’s prismatic battery cells with aluminum casing feature strong durability and high thermal conductivity along with safety-enhancing design elements such as vents and fuses.
In addition, the batteries incorporate SAMSUNG SDI’s proprietary “No TP (No Thermal Propagation)” technology, which prevents heat from spreading to adjacent cells in the event of a fire.
The No TP technology is designed to inhibit internal thermal propagation, and with SAMSUNG SDI’s proprietary thermal propagation simulation program, the battery structure can be optimally engineered to prevent fire escalation.
Known for differentiated safety technologies and high-energy density achieved with the Z Stacking method, SAMSUNG SDI’s prismatic battery is highly recognized for technological excellence in the global ESS market.
Visitors can also learn about SAMSUNG SDI’s supply chains for ESS production in the U.S. and check out award-winning products at the booth.
“At this year’s exhibition, visitors will experience SAMSUNG SDI’s differentiated ESS technologies optimized for the U.S. market,” said a SAMSUNG SDI official. “With our extensive know-how in prismatic batteries and robust local manufacturing capabilities, we are committed to further enhancing our competitiveness in the U.S., the world’s largest ESS market.”
