The Department of Defense, specifically the Army, is seeking proposals for the development of an Advanced Fiber-based Electronic Battery System through the SBIR program. The objective is to create a safe, stable, high-capacity, rechargeable fiber-based structural battery that can be integrated into Soldiers' equipment, such as rucksacks, to reduce their combat load while maintaining operational efficiency. This innovative battery system is crucial for enhancing the power supply of electronic systems used by Soldiers on the battlefield, addressing the significant weight burden of traditional batteries. Phase I proposals are invited with a funding amount of up to $250,000 for a performance period of six months, with the solicitation opening on April 23, 2025, and closing on May 21, 2025. Interested parties can find more information and submit proposals through the official DOD SBIR website.
