SBIR / STTR #A23B-T017

U.S. Army STTR for Solid-State Lithium Battery Research and Development

The U.S. Army’s Small Business Technology Transfer (STTR) opportunity seeks research and development of safer, high-energy-density solid-state lithium batteries. - Buyer: U.S. Army; the specific sub-agency or program office is not identified. - Requested work: Develop a battery concept using solid electrolytes, high-voltage cathodes, lithium-metal anodes, and conducting-polymer interfacial layers to improve charge transfer and reduce resistance. - Materials of interest include PEDOT, polypyrrole (PPy), polyaniline (PANI), quinone, polyacetylene, lignin, and sulfonated lignin. - Quantities and phases: - Phase I: Develop a concept cell and deliver 10 laboratory cells, in coin or pouch format. - Phase II: Develop 20 pouch cells, targeting more than 80% capacity retention at room temperature and 75% at 0 °C. - Phase III: Develop multilayered pouch-cell prototypes, with capacities on the order of amp-hours, for potential use in soldier-carried batteries. - Important performance goals include high energy density, safer operation, longer cycle life, and operation across a wide temperature range. - Funding is listed at up to $197,000 for Phase I. No OEMs, vendors, or part numbers are identified.

Description

The Army STTR topic seeks development of a high-energy-density, safer lithium-ion battery using solid electrolytes, high-voltage cathodes, and lithium-metal anodes. The work focuses on conducting-polymer artificial interfacial layers to improve charge transfer, reduce resistance, and support battery performance across a wide temperature range. Phase I includes designing a concept cell and delivering monthly progress reports, a final technical report, and 10 laboratory cells to the U.S. Army. The topic lists an award amount up to $197,000 and a Phase I duration of up to six months.
