Demonstrating large-scale and high-performance lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries are an exciting next step in battery technology, offering a way to surpass the capabilities of traditional lithium-ion batteries (LIBs) while reducing the reliance on scarce raw materials. These batteries hold particular promise for applications where weight is crucial, such as powered flight, which has been limited by the low energy-to-weight ratio of existing batteries. With the global battery market valued at $110 billion, it’s estimated that about one-third of this market involves weight-sensitive applications that contribute roughly 2% of global carbon emissions. Li-S batteries could be key to achieving net-zero goals by electrifying these sectors.

Building on progress from an ERC Advanced Grant, this project has made a major breakthrough with a new type of cathode material called LixMoS2. This material, free of critical raw materials, addresses long-standing challenges in Li-S battery technology, enabling batteries that are both high-energy and durable. The project’s goal is to move this innovation closer to commercial use, scaling up the production of the cathode material to kilogram levels and demonstrating large-scale Li-S batteries with excellent performance. Additionally, the project will conduct a thorough market assessment, develop a business plan, and engage with industry partners to create a clear path to market, making this advanced battery technology a reality.
