Introduction of metal (Ag, Fe, Cu) into ionite leads to the formation
of metal-containing redoxite with mixed ionic and electronic conductio
n, which is realized through counterions, metal component, and polymer
ic matrix. Overall electrical conductivity is affected by metal nature
, metal's oxidizability, its capability for forming ionic and oxide pr
oducts, as well as by steric factors (amount of metal, pore volume occ
upied by metal). An adequate amount of metal reduces activation energy
of ionite conductivity.
