Microstructural Analysis Towards Heavy Metal Recycling in Grid-Level Molten Sodium Battery Storage


EMSL Project ID
60227

Abstract

Large-scale implementation of battery storage is a necessary step towards 100% renewable electricity, 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. To optimize long-term operation and design recycling strategies towards sustainable production, understanding the distribution and characteristics of the lead content in the composite is crucial. The microscopy capability at EMSL will help to achieve this goal.
