Critical Metal Reduction in Grid-Level Molten Sodium Battery Storage
EMSL Project ID
60599
Abstract
Large-scale implementation of battery storage is a necessary step towards Net Zero, and molten sodium batteries represent one of the most competitive technologies. To enhance cell performance, heavy metals, such as lead, are often used on the anode interface. We have fabricated a novel carbon composite that significantly reduced lead loading while maintaining battery performance. Furthermore, we could replace lead with non-toxic tin. To optimize long-term operation and sustainable production, we would like to develop metal-free surface modification and understand its interaction with sodium. The microscopy capability as well as various chemical analysis instruments at EMSL will help us to achieve this goal.
