Conducting Redox Polymer as a Robust Organic Electrode-Active Material in Acidic Aqueous Electrolyte towards Polymer–Air Secondary Batteries
Kouki Oka,Kouki Oka,Christian Strietzel,Rikard Emanuelsson,Hiroyuki Nishide,Kenichi Oyaizu,Maria Strømme,Martin Sjödin +7 more
TL;DR: A conducting redox polymer (CRP) based on poly(3,4-ethylenedioxythiophene) with naphthoquinone pendant group, which is formed from a stable suspension of a trimeric precursor and an oxoammonium cation as oxidant, makes the CRP a promising candidate as anode-active material.
