Electrode structures, electrophoresis, 3D interpenetrating architectures
Batteries, capacitors, fuel cells, electrochromic displays and windows, and sensors
Need to insert a discrete separator film or electrolyte layer to fabricate electrochemical junctions
This invention concerns methods in which electrical potentials and electric fields are used in order to form electrochemical junctions between positive and negative electrodes, and electrochemical devices using these methods. Said devices may have a variety of internal designs or architectures including those of 1, 2, and 3-dimensional construction. These include laminated devices, bobbin construction batteries and variants thereof, planar interpenetrating electrode structures, and 3D interdigitated and interpenetrating structures such as those based on the infiltration of a porous electrode with an opposing electrode. The methods and devices of the invention can be "separatorless" by virtue of having an in-situ formed electronically insulating, ionically conductive layer between the anode and cathode.
