Document Language : English 
Abstract : The network polymer electrolytcs having various numbers of free-chain ends were critically photo-cross linkad in the presence of two lithium salts namely: lithium bis(trifluoromethylsulfonyl)imide (LiTFs)) and lithium tetrailuoroborate (LIBr4) have been critically investigated. Polymer network composed of mixtures of mono-acrylated (MA) and tri-acrylated (TA) copolymers of ethylene oxide and propylene oxide and the number of free-chain ends are controlled by the MA composition. The influence of the free- chain ends on the thermal property, ionic conductivity and interfacial characteristics at the lithium electrode has been discussed. In terms of thermal stability, two different types of lithium salts have been used properly to explore various contributions at electrolyte/lithium anode interface. The data revealed that, the salt LiTFSI is more stable than LiI3r4. The dependence of the salt concentration for the inverse of interfacial resistance (R1), corresponding to the exchange current showed direct relationship. The R1 values of the polymer electrolyte containing LITFsI decreased on increasing the number of freechain ends, indicating that the dissolution/deposition process is directly accelerated by ion/polymer cooperative motion. in the L113F4/poiymer mixtures at the lithium electrode interface are considered to be restrained due to the salt instability and the formation of solid electrolyte passivation layer.
