Abstract: An energy storage device can include a first electrode, a second electrode and a separator between the first electrode and the second electrode wherein the first electrode includes an electrochemically active material and a porous carbon material, and the second electrode includes elemental lithium metal and carbon particles. A method for fabricating an energy storage device can include forming a first electrode and a second electrode, and inserting a separator between the first electrode and the second electrode, where forming the first electrode includes combining an electrochemically active material and a porous carbon material, and forming the second electrode includes combining elemental lithium metal and a plurality of carbon particles.

Abstract: An energy storage device can include a cathode and an anode, where at least one of the cathode and the anode are made of a polytetrafluoroethylene (PTFE) composite binder material including PTFE and at least one of polyvinylidene fluoride (PVDF), a PVDF co-polymer, and poly(ethylene oxide) (PEO). The energy storage device can be a lithium ion battery, a lithium ion capacitor, and/or any other lithium based energy storage device. The PTFE composite binder material can have a ratio of about 1:1 of PTFE to a non-PTFE component, such a PVDF, PVDF co-polymer and/or PEO.
