New solvating cross-linked polyether for lithium batteries

A new attractive polycondensation provides cross-linked solvating polyethers. The electrolytes prepared from these networks exhibit good ionic conductivities from ambient temperature. Their thermal and electrochemical behaviour allow their use in lithium batteries. A comparison between the conductivities of lithium, sodium and potassium network electrolytes shows that lithium electrolytes are more conductive at high concentration while for O/M>20 potassium electrolytes exhibits the best conductivity.
