Title: Three-dimensional ion transport networks and current collectors for electrochemical cells

Abstract

Provided herein are three-dimensional ion transport networks and current collectors for electrodes of electrochemical cells. Exemplary electrodes include interconnected layers and channels including an electrolyte to facilitate ion transport. Exemplary electrodes also include three dimensional current collectors, such as current collectors having electronically conducting rods, electronically conducting layers or a combination thereof.
