Intrinsically conducting polymers and their combinations with redox-active molecules for rechargeable battery electrodes: an update

Intrinsically conducting polymers and their copolymers and composites with redox-active organic molecules prepared by chemical as well as electrochemical polymerization may yield active masses without additional binder and conducting agents for secondary battery electrodes possibly utilizing the advantageous properties of both constituents are discussed. Beyond these possibilities these polymers have found many applications and functions for various further purposes in secondary batteries, as binders, as protective coatings limiting active material corrosion, unwanted dissolution of active mass ingredients or migration of electrode reaction participants. Selected highlights from this rapidly developing and very diverse field are presented. Possible developments and future directions are outlined.

Automated summary

This paper discusses the potential applications and functions of intrinsically conducting polymers and their copolymers and composites with redox-active organic molecules, prepared by chemical and electrochemical polymerization, in secondary batteries. These materials can serve as active masses for battery electrodes, as well as binders and protective coatings to limit corrosion and unwanted dissolution of active materials.
