Poly(ethylene oxide) electrolytes containing mixed salts

摘要: An unusual conductivity enhancement occurs in PEO-based ZnBr2/LiBr electrolytes of composition, [xZnBr2 + (1 − x)LiBr](PEO)16 with x = 0.00, 0.05, 0.50, 0.75, 1.00. The the mixed-salt is higher than that either pure salt electrolyte. highest conductivity, observed for 0.5, two orders magnitude LiBr(PEO)16 and one order ZnBr2(PEO)16. In contrast, mixed Mg (CIO4)2/LiCIO4 electrolytes, [xMg(CIO4)2 x) LiCIO4](PEO)16 where 0.20, 0.80, 1.00, increases monotonically mole fraction component, LiCIO4(PEO)16. differential scanning calorimetry (DSC) results suggest from a change charge carrier type concentration, whereas Mg(CIO4)2/LiCIO4 arises microscopic viscosity electrolytes. © 1993 John Wiley & Sons, Inc.
