LG Chem has announced that it will unveil an integrated battery safety solution designed to delay and prevent thermal runaway during InterBattery 2026, South Korea’s largest battery exhibition, scheduled to take place from March 11 to 13 at COEX Convention & Exhibition Center.
The company’s new safety solution aims to address rising concerns around battery safety as electric vehicles (EVs) and energy storage systems (ESS) become more widely used across both consumer and industrial applications. With global original equipment manufacturers (OEMs) introducing stricter regulations related to thermal propagation, preventing thermal runaway has become a critical requirement in battery design.
At the event, LG Chem will introduce advanced engineering plastics (thermoplastics) that can delay thermal runaway. When exposed to flames, these materials form a dense protective barrier that slows the spread of flames and pressure, helping prevent heat from reaching adjacent battery cells and modules. The lightweight material also offers high processability, allowing greater flexibility in battery pack design.
The technology has already gained industry recognition, receiving the InterBattery Award in the Reliability, Safety and Sustainability category for its strong alignment with tightening global safety standards.
LG Chem will also showcase Nexula®, an aerogel-based thermal barrier material known for its superior insulation capabilities. The material effectively blocks thermal diffusion between battery cells, modules, and packs. By combining the thermal-runaway-delaying plastics with aerogel insulation, LG Chem has developed a dual-layer safety system that both delays and blocks heat propagation.
Additionally, the company will present a range of advanced adhesive solutions, including thermally conductive adhesives for efficient heat dissipation, structural adhesives for bonding dissimilar materials such as metals and plastics, and potting resins designed to protect batteries from external impacts, moisture, and ignition risks.
Under the theme “Beyond EV, Creating Tomorrow,” LG Chem’s exhibition booth will highlight advanced materials for emerging industries such as humanoid robots and urban air mobility (UAM).
The display will also feature the company’s complete battery materials portfolio, including high-nickel (High-Ni), high-voltage mid-nickel, lithium iron phosphate (LFP), and lithium manganese-rich (LMR) cathode materials, along with carbon nanotubes (CNTs), anode binders, and recycled materials—demonstrating LG Chem’s integrated capabilities across battery performance, safety, and sustainability.
