摘要: Abstract The a.c. and d.c. conductivities of salt-free LiCF 3 SO -doped linear segmented polyurethanes have been investigated. In all cases, the conductivity depends on hard segment concentration degree phase separation exhibited by these materials. A qualitative understanding behaviour systems can be obtained from free volume considerations. Increasing salt in a range 1.5 to 5 wt% LiCIO 4 produced maximum at low concentrations. comparison salt-doped with similarly doped polyethylene oxides indicated that some cases comparable were obtained. rechargeable cell containing polyurethane gave performance 389 K similar utilizing oxide electrolyte.
