Abstract
Provided are electrically conductive polymer materials that have improved long chain conductivity as well as their use in electrochemical cells and other devices. The electrically conductive polymers may be characterized by a kinking factor of 0.25 or lower representing reduced levels or the absence of contaminants or structures that interrupt conductivity in prior polymer materials. In some aspects, an electrically conductive polymer includes a cap that serves to further promote conductivity of the polymer. Also provided are electrochemical cells that incorporate the electrically conductive polymers as provided herein and methods of manufacturing such polymers.
Claims101
An electrode comprising:
- a current collector;
- and
- a film comprising an electrically conductive polymer comprising a plurality of monomers, wherein the plurality of monomers are conjugated in a polymeric linkage with a kinking factor of 0.25 or less.
An electrode comprising:
- a current collector;
- and
- a film comprising the electrically conductive polymer comprising a plurality of monomers, said electrically conductive polymer comprising a cap on one or both ends of the electrically conductive polymer.
An electrically conductive polymer comprising:
- a plurality of monomers linked to form said electrically conductive polymer, said electrically conductive polymer further comprising a cap on one or both ends of the electrically conductive polymer.
A process of forming an electrically conductive polymer comprising:
- intermixing a plurality of cap monomers and chain monomers a molar ratio of 10:100 or less, and
- polymerizing said monomers at a polymerization temperature for a polymerization time of one hour or less,
- wherein said cap monomers differ structurally from said monomers.
