What LS Materials does

LS Materials (엘에스머트리얼즈 주식회사) is a South Korea-based manufacturer of ultracapacitors (supercapacitors / Electric Double Layer Capacitors), founded in 2002 as an R&D initiative within LG Cable, transferred to LS Mtron in 2008, formally spun off as an independent subsidiary of LS Cable & System in January 2021, and listed on the KOSDAQ market in 2023. The company produces over 45 ultracapacitor cell variants across cylindrical (60mm, 50mm, 40mm, 35mm, 33mm, 22mm), PCB-mount (Snap-in / Lug), radial lead, and busbar form factors, with capacitance ratings from 5F to 3400F and voltages from 2.7V to 3.0V, leveraging electrostatic double-layer charge storage rather than chemical reactions to deliver high power density, high cycle life (1 million+), and long-term reliability.

The company's product portfolio spans individual cells, packaged modules (LSUM series), 19-inch rack and cabinet systems (LS UltraGrid), the 2024-launched Celldule (world's first combined cell-and-module package), and complete ultracapacitor systems for hybrid energy storage. Beyond the core Eco-Friendly Energy (ultracapacitor) segment, LS Materials operates two additional business segments — Eco-Friendly Materials (aluminum) and Eco-Friendly Parts (EV battery components and fuel cell desulfurization equipment) — and holds certifications including IATF 16949, ISO 14001, ISO 45001, ISO 27001, RoHS, and REACH.

LS Materials sells primarily through direct B2B channels to a base of over 500 enterprise customers across transportation, green energy, automation, and power applications, with geographic diversification across Europe (190+), Asia/China (180+), North America (100+), and other regions (50+). Recent strategic wins include a 2026 supply contract for a US nuclear fusion demonstration project and entry into the North American AI data center power supply chain via fuel cell component supply, positioning the company as an enabling supplier to next-generation power infrastructure rather than a consumer-facing AI software provider.

Core offering

LS Materials manufactures ultracapacitors (supercapacitors/EDLCs) for enterprise customers, producing over 45 cell variants in cylindrical (60mm, 50mm, 40mm, 35mm, 33mm, 22mm diameters), PCB-mount, radial lead, and busbar form factors with capacitance from 5F to 3400F and voltages from 2.7V to 3.0V. The company also offers packaged modules, the world's first "Celldule" cell+module combination, 19-inch rack and cabinet systems, and complete energy storage systems targeted at AI data center power stabilization, grid energy storage, industrial backup power, renewable energy integration, and transportation applications.

Product overview

LS Materials is a manufacturer of ultracapacitors (supercapacitors), which are energy storage devices positioned between traditional capacitors and rechargeable batteries. The company produces over 45 different cell variants across multiple series (60Ø, 35Ø, 33Ø, 22Ø, and Lead/Radial types), along with modules, the world's first Celldule (cell+module combination), and complete systems. The product portfolio includes cylindrical cells ranging from 5F to 3400F capacitance, BusBar type, PCB mounting type, and radial lead configurations with voltage ratings from 2.7V to 3.0V. Additionally, the company operates three business segments: Eco-Friendly Energy (ultracapacitors), Eco-Friendly Materials (aluminum), and Eco-Friendly Parts (EV battery components).
