Abstract:
Percolation effects observed in the ionic conductivity variation with
oxide volume fraction in "soggy sand" electrolytes [A non-aqueous
electrolyte and a battery, a supercapacitor, and electrochromic device
and a solar cell including such an electrolyte, Aninda Bhattacharyya
and Joachim Maier, GI-Nr.: 3170 GBC; European Patent application-2003
EPA 03018161; US application filing-2004, A.J. Bhattacharyya, J. Maier,
Adv. Mater. 16 (2004) 811] are discussed in the light of conductivity
and theological measurements. The enhancement in ionic conductivity of
the composites is attributed to the formation of a percolating
attractive network of insulating particles. (c) 2006 Elsevier B.V. All
