The Defense Advanced Research Projects Agency (DARPA) is seeking information on independent verification and validation (IV&V) capabilities for testing and evaluation of flexible and malleable batteries. This Request for Information (RFI) aims to gather insights from stakeholders in industry, academia, and government labs regarding the unique challenges posed by these advanced battery systems, particularly in relation to mechanical testing and battery discharge monitoring. The information collected will inform future DARPA solicitations on related topics, with responses due by April 21, 2025. Interested parties can reach out to the MTO BAA Coordinator at DARPA-SN-25-64@darpa.mil for further details.
