A stt-uctwrai model to calculate the electroclicrnical itltcrl'ace artx for a car~tpxitt:graphite electrode is dcscribed. A new ccpalion sing the niodcl predicted arca tocalculate uhen~ical dihsiou cocfficicnt L I , , , , eljn-tinates tl~c effccts Ifonl hb~.iciktionsuch as active inass (mB) aid g~omctric area (,,). The chcmical diffusion coeflicicntvalues ~alculated fur graphite clectrodcs of different tliick~~csscs and porosities tising thcnew equalion are almost same as expected.
