摘要:
The present invention includes three-dimensional secondary battery cells comprising an electrolyte, a cathode, an anode, and an auxiliary electrode. The cathode, the anode, and the auxiliary electrode have a surface in contact with the electrolyte. The anode and the cathode are electrolytically coupled. The auxiliary electrode is electrolytically coupled and electrically coupled to at least one of the anode or the cathode. Electrically coupled means directly or indirectly connected in series by wires, traces or other connecting elements. 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 means the average of the shortest path for ion transfer from every point on the coupled cathode or anode to the auxiliary electrode.
