Zeta Energy and Huntsman Demonstrate a Major Step Towards a Critical Metal-free Battery with Carbon Nanotubes

Zeta Energy and Huntsman Corporation have made a significant advancement in battery technology by demonstrating a lithium-sulfur battery that eliminates the need for critical metals copper and aluminum, traditionally used as current collectors, thereby enhancing the battery's energy and power density. This innovation is especially critical as copper is considered a "critical material" due to its essential role in energy technologies and the potential for supply chain disruptions. By utilizing carbon-based current collectors instead of metal, the new lithium-sulfur battery not only avoids the use of critical metals but also increases the energy density beyond what Zeta Energy's previous lithium-sulfur batteries achieved. Huntsman's MIRALON® carbon nanotube materials played a key role in this development, offering a lightweight and effective alternative that could enable future metal-free batteries with energy densities exceeding 500 Wh/kg, marking a pivotal step towards more sustainable battery production.
