Considerable attention is currently focused on inorganic conducting solids from both a fundamental standpoint and for their use in high energy density batteries. Polymers with low glass transition temperatures (Tg) and a high concentration of polar groups, are good candidates for electrolyte use. Phosphazene based polymers are attractive on three counts: 1) The linear chlorophosphazene can be modified chemically to yield a wide range of substituted polymers. 2) The high molecular weight polymers produced are stable and not crosslinked. 3) Fully substituted phosphazene polymers have been produced with Tg's of minus 100 degree C and lower. The effects of different sidechain lengths on ionic conductivity, physical properties, and the tendency to form salt complexes will be discussed. Influence of various cations and anions on transference numbers will also be discussed.
