Preparation of pan:ec:pc:LiTf polymer electrolytes and characterization of Li/pan:ec:pc:LiTf/PPy:dbs cells

摘要

At present, a considerable attention is focussed on developing polymer electrolytes with good ionic conductivities at ambient temperatures and on all polymer lithium cells where both the electrolyte and the cathode are made of polymers. The present study is based on the synthesis of the gel electrolyte, PAN : EC : PC : LiCF_3SO_3 (Lithium Triflate - LiTf) and characterization of lithium cells based on these electrolytes and polypyrrole (PPy) conducting polymer cathde. The composition of the gel polymer electrolte which gives the maximum room temperature conductivity was foudn to be 15mol
