Development of Lithium-Ion Cells for High Rate Pulse Power Applications

A novel approach for the development of a lithium-ion battery system is proposedfor pulse power aerospace applications. The approach involves fabrication ofthin-film electrodes with nano-particles cathode and anode materials having highcapacity and high rate capability, use of high lithium-ion conductive electrolyte,fabrication of prismatic design pouch cells, and testing of the developed cells todemonstrate the proof-of concept. The thin film electrodes will be characterizedusing different analytical and electrochemical techniques.The rechargeable battery market is growing rapidly and lithium-ion batteries aretaking over the market share from Ni-MH and Ni-Cd even with the higher cost. Thesuccessful completion of Phase I work will demonstrate the feasibility of developinga new high specific power rechargeable lithium-ion battery system. The rechargeablelithium-ion batteries developed with the proposed nanoparticles cathode and anodematerials will provide superior specific power to the present state-of artrechargeable batteries and will have a broad commercial applications to the growingdemand of high power portable electronic devices.
