摘要: Solid Polymer blend electrolytes based on Polyvinyl alcohol (PVA) and Polyethylene glycol (PEG) complex with Mg(CH3COO)2 at different weight percent ratios were prepared using solution cast technique. Conductivity in the temperature range 303-373 K transference number measurements have been employed to investigate charge transport this solid polymer electrolyte system. The highest conductivity is found be 3.23 x 10 -5 S/cm 373K for sample 30 of PVA/PEG matrix. Transport data shows that system predominantly due ions. Using electrolyte, an electrochemical cell configuration Mg /(PVA+PEG+Mg(CH3COO)2)/ (I2+C+electrolyte) was fabricated its discharge characteristics profile has studied. Copyright © 2012 VBRI Press.
