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.
