“…In electrodeposition, dendritic growth is often observed together with hydrogen-gas evolution5678910. Dendrite formation is therefore quite popular in zinc deposition8910, of which reduction potential is much more cathodic than the normal hydrogen potential (NHE).…”

“…Dendrite formation is therefore quite popular in zinc deposition8910, of which reduction potential is much more cathodic than the normal hydrogen potential (NHE). Even in copper deposition whose equilibrium potential is more anodic than NHE, if the electrode potential is shifted to much more cathodic side than NHE, dendrite easily emerges with hydrogen evolution567.…”

Ionic vacancy is a by-product in electrochemical reaction, composed of polarized free space of the order of 0.1 nm with a 1 s lifetime, and playing key roles in nano-electrochemical processes. However, its chemical nature has not yet been clarified. In copper electrodeposition under a high magnetic field of 15 T, using a new electrode system called cyclotron magnetohydrodynamic (MHD) electrode (CMHDE) composed of a pair of concentric cylindrical electrodes, we have found an extraordinary dendritic growth with a drastic positive potential shift from hydrogen-gas evolution potential. Dendritic deposition is characterized by the co-deposition of hydrogen molecule, but such a positive potential shift makes hydrogen-gas evolution impossible. However, in the high magnetic field, instead of flat deposit, remarkable dendritic growth emerged. By examining the chemical nature of ionic vacancy, it was concluded that ionic vacancy works on the dendrite formation with the extraordinary potential shift.
