Electrode including a 3D framework formed of fluorinated carbon

摘要

One example includes a battery case sealed to retain electrolyte, an electrode disposed in the battery case, the electrode comprising a framework defining open areas disposed along three axes (“3D framework”) formed of fluorinated carbon including elements that each include a conductive core at least partially surrounded by an electrochemically active portion, wherein a plurality conductive cores form an electrically conductive network, a conductor electrically coupled to the electrode in electrical communication with the conductive network and sealingly extending through the battery case to a terminal disposed on an exterior of the battery case, a further electrode disposed in the battery case, a separator disposed between the electrode and the further electrode and a further terminal disposed on the exterior of the battery case and in electrical communication with the further electrode, with the terminal and the further terminal electrically isolated from one another.
