Abstract
Positron annihilation lifetime spectra and ionic conductivity have bee n measured for poly(ether-urethane)-LiClO4 as a function of temperatur e. The effects of Li salt on glas transition free volume and ionic con ductivity have been discussed. A correlation between fractional free v olume and ionic conductivity was first experimentally confirmed by usi ng the free volume theory.
