SINGLE-ION CONDUCTIVITY IN POLY (LITHIUM PROPIONATE METHYL SILOXANE)

Received Date: 17 February 1992

Poly(lithium propionate methyl siloxane )as a single-ion carrier source was synthesized. The crosslinked film showed lower lithium ionic conductivity at room temperature (about 10-10 S/cm). However,the lithium ionic conductivity was obviously increased by blending with high polar polymers such as polyethylene oxide, poly (methylsiloxane - co- ethylene oxide) and poly (methylsiloxane- g- ethylene oxide). In the blend system a high conductivity of 10-7-10-5 Scm-1 at room temperature was obtained and the single-ion conductivity was deeply influenced by the content of the poly (lithium propionate methyl siloxane).The dc ionic conductivity of the flexible crosslinked films is more stable over time.
