Abstract:

U.S. Ballistic Missile Defense Organization BMDO has requirements for pulse power sources of high specific power and specific energy for applications in electric weapons, sensing, and communications systems. These objectives can be met by thin film, high temperature battery components such as a lithium-insertion anode, a lithium intercalation cathode and a high conducting Li ion electrolyte separator. This Phase I program focussed on a new class of Li ion conducting compounds and solid electrolytes made from these compounds using polymer gels. The inorganic Li conductors, which are excellent gel formers, have interesting crystal structures and are thermally and electrochemically stable. The electrolyte separators of 100-200 micrometers thickness, made from these inorganic compounds incorporated in polymeric gels utilizing lithium salts and plasticizer-solvents, have exhibited ionic conductivity of 5x10exp -3 Scm at 100 deg C.
