ZEBRA Project: History and Current Status

The ZEBRA project, which stands for Zeolite Battery Research Africa, was initiated in South Africa in 1985 with the goal of developing a high-performance Na-ion battery for electric vehicles and stationary energy storage. The project focused on a unique battery chemistry utilizing a molten salt electrolyte and a sodium-nickel chloride positive electrode. This technology offered several advantages, including high energy density, long lifespan, and good thermal stability. However, the ZEBRA battery also faced challenges related to operating temperature and cost. Despite these challenges, the ZEBRA project made significant contributions to the development of Na-ion battery technology, laying the foundation for further research and development in this field. SaNaFe Labs aims to build on this legacy by further advancing Na-ion battery technology and tailoring it to the specific needs of the stationary energy storage market.
