New poly(acrylamide) based (polymer in salt) electrolytes: preparation and spectroscopic characterization

The present paper deals with the synthesis and characterization of novel polymer in salt electrolytes based on a poly(acrylamide) matrix. The effect of the type of lithium salt and its concentration on the conductivity and microstructure of the studied electrolytes is analyzed. To this end impedance spectroscopy, infra-red spectroscopy, DSC and Maldi-ToF techniques are used. The highest conductivities achieved exceeded 10−4 S/cm at ambient temperatures. The high values of decoupling index are evidences of predominantly cationic transport in the studied electrolytes.
