This patent describes an electrochemical cell having a positive terminal, a negative terminal, and at least two electrodes comprising: an anode connected to the negative terminal; a cathode connected to the positive terminal; a separator interposed between the anode and cathode; a nonaqueous electrolyte; a first segment of exposed inert conductive metal coupled mechanically and electrically to the cathode; and an inert metal dendrite target comprised of a second segment of exposed inert conductive metal coupled mechanically and electrically to the anode. The position of the first segment of inert metal coupled to the cathode and the position of the second segment of inert metal coupled to the anode are such that the first segment and the second segment face each other and are held in physical separation by the separation. During voltage reversal a dendrite will grow from the first segment toward the dendrite target and come in contact with the dendrite target.
