Poly Ethylene

A kind of comb-shaped poly(oxyethylene) with nine oxyethylene units in ether side chains has been synthesized via chemical modification on ethylene oxide-epichlorohydrin copolymer [P(EO/EH)s] with a kind of alcohol ether carboxylate. The prepared polyether was characterized by FTIR spectroscopy. A series of polymer electrolytes were prepared by dissolving LiN(SO2CF3)2 at different ratios in the polymer matrix. It is found that the ionic conductivity of the comb-shaped poly(oxyethylene) based polymer electrolytes could reach 4.3×10-5 S/cm at 30°C and 6.2×10-4 S/cm at 80°C, which increase by an order of magnitude compared with that of poly(ethylene oxide) (PEO) based ones at corresponding temperatures. Both the amorphous feature of the polymer electrolytes above the ambient temperature and the highly mobile ether side chains of the comb-shaped polyether contribute to the increase of ionic conductivity.

Poly Ethylene

Cell failure of polymer electrolytes is rather the result of short circuits instead of assumed electrolyte oxidation. A spacer with a constant and defined distance can avoid this failure, thus realize a benchmark system for a more systematic R&D.
