Abstract

Abstract: Aseries of oxymethylene-linked polyoxyethylene multiblock polymer were synthesized by condensing dichloromethane with poly (ethylene glycol)(PEG) of different mol.wt.in the presence of potassium hydroxide powder. The multiblock polymer exhibited a certain crystallinity, and its LiClO₄ complex showed a high room temperature conductivity.Alithium battery has been constructed using LiClO₄ complex of the multiblock polymer as the electrolyte and Na_1+x V₃O₈ composite as the cathode.The performance of the battery has been investigated.

Key words: Polyoxyethylene, Block polymer, Solid polymer electrolyte, Lithium battery
