I'm seeking EV battery professionals, including legal experts, to share insights for a story examining the growing second-life EV battery market in the United States. Relevant professionals are welcome to pitch, as well as anyone currently using a second-life EV battery who'd like to share ownership perspectives. My main questions are: 1) What is driving the rapid growth of the second-life EV battery market right now, and how much supply is expected to come online in the next 5–10 years? 2) What are the biggest safety risks associated with second-life EV batteries, particularly related to degradation, thermal runaway, or unknown usage history? 3) How reliable are current methods for assessing a used EV battery’s state of health, and are there gaps in testing standards? 4) What federal or state-level guidelines currently govern the resale, transport, and reuse of EV batteries, and where are the biggest regulatory gaps? 5) Do you see a need for something like a “battery passport,” or traceability system to ensure safety and transparency? 6) How cost-competitive are second-life batteries compared to new lithium-ion systems in energy storage applications?
