Abstract
A series of PEO-PDMS polymer electrolytes were prepared. The optimum ratio of PDMS was determined according to the result of electrochemical performance tests on PEO-PDMS polymer electrolyte. Then the ionic liquid composite polymer electrolytes were synthesized by adding [BMIM]TFSI or PP 13TFSI to PEO-PDMS. The introduce of ionic liquid increases the ionic conductivity of polymer electrolyte significantly. The sample PPP-100% reaches 5.6×10 -4S/cm at room temperature. Meanwhile, all samples exhibit good thermal and electrochemical stability. Through comparing, it is found that PP13 TFSI composite polymer electrolyte has better performance, and is hopefully to be used as new polymer electrolyte in lithium batteries.
