Li-ion 6T Battery Focused Open Topic
SBIR Opportunity Analysis
The Department of the Army is seeking small business Phase I solutions under SBIR topic A254-P050 for MIL-PRF-32565 Li-ion 6T batteries. The topic targets four problem areas: wireless or power-beaming trickle charging for aggregated storage, thermal runaway and fire-mitigating materials that fit within the existing case, automated maintenance and repair tools with prognostics and diagnostics, and compact external devices to combine diverse batteries for higher-voltage bus use. The effort is Phase I only and is framed as a feasibility study, with emphasis on practicality in military environments, compatibility with Gen 3 Li-ion 6T batteries, and solutions that can support at least 48VDC bus operation without changing cells or chemistry for the fire-mitigation concept. Proposals are due by May 13, 2026, and Phase I awards may be funded up to $250,000 for a six-month period of performance.
