Li-S Energy Limited (LIS) was created through the collaboration of specialist nanomaterials scientists from Deakin University Institute of Frontier Materials and BNNT Technology Limited, under their parent company PPK Group. They developed a lightweight lithium-sulfur battery with a cycle life approaching that of lithium-ion batteries. Deakin University contributed over a decade of research into Boron Nitride Nanotubes (BNNTs) and advanced battery technologies, while BNNT Technology Limited pioneered a cost-effective, high-volume manufacturing method for BNNTs.
