Lithium-sulfur is seen as one of the most promising chemistries for the next generation of batteries, and the UK battery firm OXIS Energy has been developing the technology for some time. Now OXIS has announced that it will be one of 13 European partners in the Lithium Sulfur for Safe Road Electrification (LISA) project, which has a budget of €7.9 million, and aims to advance the development of Li-S battery cells with hybrid solid-state non-flammable electrolytes.
Today’s Li-S cells are twice as light as conventional Li-ion cells, and have reached only 10% of the theoretical specific energy of sulfur (2,600 Wh/kg). OXIS believes that an energy density of 600 Wh/kg is achievable by improving materials, components and manufacturing. LISA will incorporate process concepts designed to enable the integration of Li-S technology in future manufacturing lines.
“The LISA project ties in perfectly with OXIS Energy’s future business strategy in entering into the electric automotive sector, including trucks and buses,” said Steve Rowlands, Deputy CTO at OXIS. “Continuing our collaborations with LEITAT, Arkema, Cranfield University, IWS Fraunhofer and Renault is an exciting prospect in taking OXIS technology to the next level in terms of safe automotive electrification.”
