A direct current pulse technique to enhance conductivity of heterogeneous electrolytes

A heterogeneous electrolyte comprised of PEG(6000):LiClO4 (8:1)–MgO (20 wt.%) was prepared and characterized. The electrolyte was subjected to a DC potential of 10 mV and the effect of the potential on conductivity evolution was investigated. The DC potential enhanced the conductivity by a factor of 25. The enhancement in conductivity was due to the formation of space charge around MgO that resulted in the development of an internal field.
