Abstract:
1. A three-dimensional secondary battery cell comprising: an electrolyte; a cathode, having a surface in contact with the electrolyte; an anode, having a surface in contact with the electrolyte and wherein the anode is electrolytically coupled to the cathode; and an auxiliary electrode, having a surface in contact with the electrolyte, wherein the auxiliary electrode is electrically coupled and electrolytically coupled the cathode and/or to the anode, and the average distance between the surface of the auxiliary electrode and the surface of the coupled cathode or the coupled anode is between about 1 micron and about 10,000 microns, the average distance between the surface of the auxiliary electrode and the surface of the coupled cathode or the coupled anode being the average of the shortest path for ion transfer from every point on the coupled cathode or anode to the auxiliary electrode.
