Queensland, Australia-based materials company AnteoTech has signed a strategic collaboration and sales agreement term sheet with South Korean separator specialist Xerabrid Corporation to jointly develop next-generation lithium-ion battery separator technology. The deal, first reported by Stockhead, has since been corroborated by other financial and industry sources including TipRanks and AnteoTech’s own ASX (Australian Securities Exchange) and corporate announcements.
Under the agreement, AnteoTech’s Anteo S cross-linking separator additive will be combined with Xerabrid’s ceramic-coated separator technology. The companies said the collaboration is intended to improve thermal and mechanical stability in lithium-ion cells while reducing the risk of thermal runaway.
The companies plan to jointly develop, test and market the technology for use in battery energy storage systems, electric vehicles and consumer electronics applications.
AnteoTech strengthening its position in South Korea’s battery supply chain
AnteoTech said the agreement strengthens its position in South Korea’s battery supply chain at a time when separator manufacturers are under pressure to improve safety and performance in higher-energy-density cells. South Korea remains one of the world’s most important battery manufacturing hubs, home to companies including Samsung SDI, LG Energy Solution and SK On.
The separator market has become increasingly competitive amid weaker EV demand and oversupply concerns. In March, South Korean separator manufacturer SK IE Technology sharply reduced the value of a major separator supply agreement after customers scaled back investments.
Against that backdrop, companies are increasingly focusing on differentiated separator technologies, particularly ceramic coatings and functional additives designed to improve safety and compatibility with fast charging and high-energy chemistries.
According to TipRanks, AnteoTech said multiple separator manufacturers in South Korea and the United States are already evaluating Anteo S, with at least one customer progressing to pilot-scale testing.
AnteoTech is also developing silicon-dominant anode technologies under its Ultranode platform as part of a broader push into next-generation battery materials.
