Contribution of polyoxyethylene macromonomers to solid polymer electrolytes
The behaviour of solid polymer electrolytes based on POE and a lithium salt are strongly dependant on the processes of recrystallisation of the polymer chains. These can be reduced by the use of a blend comprising high molecular mass POE, an elastomer and a macromonomer of POE. The impedance analysis of these new solid electrolytes shows that the ionic conductivity, and also the interface transport, are governed by the content of the amorphous phase in the electrolyte environment, which can be modified by the proportion of macromonomer. Moreover, the conductivity follows an Arrhenius-type law rather than one of free volume, because of the reduced mobility of the polymer chains.
