✦ Synopsis

Cross-linked ethoxy-ethoxy-ethoxy-vinyl

ether polymers have been synthesized and complexed with lithium salts (eg LiClO, of LiBF,) to form a new class of polymer electrolytes. The characteristics of these electrolytes have been investigated in terms of ionic conductivity, lithium ion transport number and electrochemical properties. The conductivity at room temperature is three orders of magnitude higher than that of 'classical" polyethyleneoxide-based electrolytes. Preliminary results indicated that these improved, low temperature conducting electrolytes are suitable for practical applications, such as in rechargeable lithium batteries.
