Abstract

See full text

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. Methods of fabricating the anode and/or the cathode of the energy storage device are also disclosed.
