摘要: Gel polymer electrolytes are known to be very suitable for many electrochemical devices. They Gel They have been extensively studied lithium based cells. But, due several drawbacks of cells such as safety issues, handling problems and toxicity, it is the time develop non Li In this study, ionic conductivity a gel electrolyte (GPE) on polymethylmethacrylate, ethylene carbonate, propylene carbonate tetrapropylammonium iodide its performance in an Mg / C: I 2 cell was investigated. GPE prepared by varying salt concentration using hot pressed method composition, 20 PMMA 30 EC PC 40 Pr 4 N + showed highest 5.02 x 10 -3 Scm -1 at 28 ° C. The form C+I average open circuit voltage 1.9 V. short current 3.3 mA. It possible observe good stability self discharge characteristics cell.
