NEW SOLVATING CROSS-LINKED POLYETHER FOR LITHIUM BATTERIES

A new attractive polycondensation provides cross-linked solvating poly ethers. The electrolytes prepared from these networks exhibit good ion ic conductivities from ambient temperature. Their thermal and electroc hemical behaviour allow their use in lithium batteries. A comparison b etween the conductivities of lithium, sodium and potassium network ele ctrolytes shows that lithium electrolytes are more conductive at high concentration while for O/M>20 potassium electrolytes exhibits the bes t conductivity.
