A new current line division concept for the determination of the current distribution in electrochemical cells. Part I. Theoretical background of the corner weakness effect in electroforming

A new approach to the determination of the current distribution in electrochemical cells, the current line division concept, is introduced. The new concept, based on the basic equations of electrics and electrochemical kinetics, was employed for a theoretical explanation of the phenomenon known in electroforming as corner weakness . It was shown that this phenomenon depends on the kind of control of the deposition process, being the largest in the case of pure ohmic control and disappearing in the case of pure activation control.
