Battery supply chains are rapidly evolving, with growing focus on critical minerals, domestic manufacturing, and end-to-end transparency. This session will cover the basics State Energy Offices need to know—critical mineral extraction and sourcing, emerging battery labeling and data transparency efforts, and key safety and cost considerations across manufacturing, transport, use, and storage. Attendees will leave with practical insights to inform program design, procurement, and stakeholder coordination while advancing safe, responsible electrification and economic development efforts.
