LG Chem announced that it will showcase an integrated safety materials solution designed to reduce battery fire risks at InterBattery 2026, which will be held from March 11 to 13 at COEX in Seoul.
The company plans to introduce advanced materials that delay and block battery thermal runaway, a key safety issue for electric vehicle (EV) batteries and energy storage systems (ESS). As EV and ESS adoption continues to expand worldwide, battery safety has become a critical factor influencing not only technology competition but also market trust. Global automotive manufacturers are also strengthening thermal propagation regulations, making thermal runaway mitigation an essential element of battery design.
At the exhibition, LG Chem will present its engineering plastic material called SFB, which is designed to delay thermal runaway. When exposed to flames, the material forms a dense and rigid barrier on its surface that slows the transfer of flames and pressure. The lightweight and highly processable material also provides greater design flexibility for battery packs.
The technology has been recognized for its ability to respond to tightening global battery safety regulations and recently received an InterBattery Award in the reliability, safety, and sustainability category.
LG Chem will also introduce Nexula, an aerogel-based thermal insulation material. Aerogel can effectively block heat transfer not only between battery cells but also within modules and battery packs. According to the company, combining SFB and Nexula enables a dual safety system that both delays and blocks heat propagation.
In addition to these materials, LG Chem will display various adhesive solutions designed to enhance battery stability. These include thermal conductive adhesives for battery cell stabilization, structural adhesives for bonding dissimilar materials such as metals and plastics, and potting compounds that protect batteries from external shock, moisture, and ignition risks.
At its booth on the third floor of COEX, LG Chem will also present a broader advanced materials portfolio under the theme “Beyond EV, Creating Tomorrow.” The display will highlight materials applicable to future industries such as humanoid robots and urban air mobility (UAM), as well as EV technologies.
The company plans to showcase a wide range of battery materials covering the entire value chain, including cathode materials such as high-nickel (High Ni), high-voltage mid-nickel (HV Mid Ni), lithium iron phosphate (LFP), and lithium manganese rich (LMR), along with carbon nanotubes (CNT), anode binders, and recycled materials.
Kim Dong-chun, President of LG Chem, said that as batteries become more integrated into everyday life, safety and reliability are becoming core competitive factors. He added that the company will continue strengthening its leadership in the global market through advanced materials technology and integrated solutions.
