Gelion, an Anglo-Australian battery technology company, has announced the successful fabrication of advanced sulfide-based solid-state separators. This development, achieved using intellectual property (IP) licensed from Oxford University Innovation Limited, marks a significant step toward enhancing the durability and energy density of lithium metal batteries, particularly in Gelion’s high-energy GEN 3 lithium-sulfur (LiS) cells.
Solid Electrolyte Separators (SES) are essential components in long-lasting, high-energy lithium metal batteries due to their capacity to improve safety, extend cycle life, and increase energy density. However, the commercial application of SES has faced challenges due to difficulties in manufacturing and processability. Gelion’s successful fabrication of this SES component represents progress in overcoming these limitations.
The new technology could open additional revenue opportunities through licensing to Lithium nickel manganese cobalt oxide (Li-NMC) battery manufacturers, enabling scaled SES production. It also supports the integration of SES into liquid-based lithium-metal batteries (such as Li-NMC and lithium-air technologies) and into solid-state Li-ion/Li-S cell assemblies. Additionally, the improved SES design allows for more relaxed operational conditions, such as reduced pressure and temperature requirements, making solid-state battery technology more commercially viable.
OXLiD Ltd, a subsidiary of Gelion plc, has developed a lightweight, ultra-thin, and flexible solid electrolyte system. This innovation validates Oxford University’s intellectual property and marks a significant advancement in high-energy, long-cycle batteries tailored for aerospace and automotive applications.
The newly developed solid-state separator enhances the performance and safety of lithium-sulfur (Li-S) and lithium nickel manganese cobalt oxide (Li-NMC) batteries. By leveraging cutting-edge research from Oxford University, Gelion aims to address critical challenges in energy storage, including increased energy density, prolonged cycle life, and improved operational safety.
This development underscores Gelion’s commitment to delivering innovative energy solutions and strengthens its position in the rapidly evolving battery technology market.
