Risk Mitigation and Design Alternatives for Non-flammable HA Cells for Navy Applications

Physical Sciences Inc. (PSI) will construct and deliver a distinct non-flammable lithium metal cell design that exceeds the functional, performance and form factor requirements of the Barracuda system. The design will employ PSI’s proprietary high active (HA) coated materials and nonflammable electrolyte to produce safer cells with enhanced energy and power density. The HA technology has been demonstrated in multiple cell formats to deliver enhanced energy and power density. The PSI electrolyte has been demonstrated to be nonflammable as an aerosol, a liquid, and on ejection from a functioning cell. PSI will carry out performance and safety testing at targeted operating temperatures using simulated power profiles developed together with Raytheon IDS (RTN). This testing will determine the achievable increase in mission operation time enabled by the PSI cell design.
