Several network-based polymer electrolytes provide both thermal, mecha
nical and redox stabilities, while insuring a high conductivity level.
Linear unsaturated polyether precursors may be obtained either by ste
p-growth polymerization from oligomeric polyethers or by ring-opening
polymerization from oxirane mixtures. In addition, theoretical investi
gations on several lithium salts are presented, which allowed optimize
d geometries as well as charge densities to be established in the gas
phase. (C) 1997 Elsevier Science S.A.
