LG Chem is set to reveal a new integrated battery safety solution designed to delay and block thermal runaway, as the company takes the stage at InterBattery 2026, South Korea’s largest battery exhibition, running March 11–13 at COEX Convention & Exhibition Center in Seoul.
The system aims to tackle one of the biggest safety challenges facing modern batteries — thermal runaway — at a time when electric vehicles and energy storage systems are rapidly expanding across industries and everyday life.
As global automakers tighten safety standards around thermal propagation, manufacturers are under growing pressure to integrate technologies that can prevent heat and flame from spreading between battery cells and modules.
At the exhibition, LG Chem will showcase a thermal-runaway-delaying engineering plastics technology that forms a dense protective barrier when exposed to flames. The material is designed to slow both flame and pressure propagation, helping prevent heat from spreading to neighboring battery cells. The lightweight thermoplastic material also offers high processability, allowing greater design flexibility in battery pack architecture.
The technology has already gained industry recognition, winning the Reliability, Safety and Sustainability category at the InterBattery Awards.
“As batteries become more deeply embedded in our daily lives, safety and reliability are becoming core competitive advantages,” said Kim Dong-choon, CEO of LG Chem. “LG Chem will continue to strengthen its global market leadership through core materials competitiveness and technology-driven integrated solutions.”
Alongside the new engineering plastics technology, the company will also present Nexula®, an aerogel-based thermal barrier material designed to block heat transfer between battery cells, modules and entire packs. Combined with the thermal-runaway-delaying materials, the aerogel insulation forms a dual-layer safety system aimed at both delaying and blocking heat propagation.
The showcase will also include a suite of battery adhesive technologies. These range from thermally conductive adhesives that dissipate heat while securing battery cells, to structural adhesives that bond metals and plastics to strengthen battery systems, and potting resins that protect batteries from external impacts, moisture and ignition risks.
Under the theme “Beyond EV, Creating Tomorrow,” LG Chem will also highlight advanced materials targeting emerging industries such as humanoid robots and Urban Air Mobility.
