Abstract
The present disclosure provides a composite material comprising an electrically conductive polymer, such as poly(3,4-ethylenedioxythiophene) (PEDOT) and an ionically conductive polymer, such as poly(ethylene oxide) (PEO). This composite forms a dual conductor for three-dimensional electrodes in electrochemical applications including lithium ion batteries.
Claims27
A composite material for an electrode, comprising a polymer matrix, the polymer matrix comprising:
- a first phase, the first phase comprising an electrically conductive polymer, wherein the first phase is substantially continuous;
- and
- a second phase, the second phase comprising an ion-conducting polymer.
