Paper Abstract

Building battery architectures with functional interfaces that are interpenetrated in three dimensions opens the door to major gains in performance as compared to conventional 2-D battery designs, particularly with respect to the battery footprint. We are developing 3-D solid-state Li-ion batteries that are sequentially assembled from interpenetrating and tricontinuous networks of anode, cathode, and electrolyte/separator materials. We use fiberpaper- supported carbon nanofoams as a massively parallel, conductive, ultraporous base platform within which to create the 3-D cell. The components required for battery operation are incorporated into the x,y,z-scalable papers and include nanoscale coatings of metal oxides that serve as Li-ion-insertion electrodes and ultrathin, electroninsulating/ Li-ion conducting polymer coatings that serve as the electrolyte/separator.
