Nonflammable Battery

Physical Sciences Inc. (PSI) will demonstrate a non-flammable, high power rechargeable battery design capable of 20C discharge rates after activation from an inert, inactive state. This battery will be constructed by combining PSIs non-flammable electrolyte and high active (HA) coating technologies. During the Phase I, PSI will demonstrate that the electrolyte is non-flammable both as an aerosol and on ejection from a cycled battery. Optimized HA electrodes will be prepared and used to construct coin and pouch cells to demonstrate the ability of the cell design to deliver the targeted rate performance. PSI will demonstrate the battery can be stored in an inert, inactive state and that the targeted performance can be achieved after rapid activation. The results of the lab scale tests will be used to design a prototype battery for an Air Force/ICBM identified application. Successful completion of these efforts will demonstrate the readiness of the technology for further scale-up and demonstrations in Phase II.
