Polymeric electrolytes for ambient temperature lithium batteries. Final report

PDF Version Also Available for Download.

Description

Samples of a plasticized Li{sup +} polymer electrolyte having high conductivity at room temperature were prepared with mixed plasticizer compositions of ethylene carbonate (EC) and propylene carbonate (PC). The influence of EC:PC in varying proportions with 1M LiAsF{sub 6} as the dissolved salt on the chemical and electrochemical properties of the electrolyte was studied. Electrolytes with mixed EC:PC compositions were found to have greater thermal stability, improved lithium and cathode (V{sub 6}O{sub 13}) interfacial properties, and superior mechanical properties compared to those prepared with pure EC and PC. The results of this work are relevant to possible uses of such ... continued below
