Safe, On Demand High Energy Power System

Power systems offering higher energy and power densities are necessary to meet the demands of next generation electrical devices. Physical Sciences Inc. (PSI) will combine together a metal anode and lithium metal oxide fiber cathode to form a power system offering enhanced energy (>260Wh/kg) and power density (>2600W/kg). During the Phase I, PSI will demonstrate the ability to charge the power source from a fully discharged, inert state to a fully charged, operational ready state in less than 2 minutes. PSI will demonstrate discharge rates of 10C and greater for the system while delivering high energy density. The low cost cathode fibers will allow for enhanced rate capability as compared to traditional materials. Construction of 100+mAh cells and the subsequent testing will demonstrate the ability to deliver the required performance. Using the generated data, a power system will be designed and the performance predicted. During the option effort, the prototype system will be constructed and used to power a laser source. Testing in a simulated high altitude environment will demonstrate the ability to operate in the target environment. Successful completion of these efforts will demonstrate the readiness of the technology for further scale-up and demonstrations in Phase II.
