Electrochemical Characteristics of Poly(trans‐1,2‐di(2‐thienyl)ethylene) and Its Battery Application

Abstract
The electrochemical characteristics of poly(trans‐1,2‐di(2‐thienyl)ethylene) and its battery characteristics have been studied. Poly(trans‐1,2‐di(thienyl)ethylene)s prepared from both trans ‐1,2‐di(thienyl)ethylene and cis ‐1,2‐di(thienyl)ethylene show reversible doping‐undoping behavior and excellent charge‐discharge characteristics such as a coulombic efficiency greater than 99% and a stable electrode potential even under a large charge‐discharge current. A higher charge‐discharge capacity is observed in nitrobenzene solution than in propylene carbonate solution. The dependence of the charge‐discharge characteristics on the configuration of the monomer used in the polymer synthesis has been discussed in terms of the difference in diffusion coefficient of dopant ion in the polymer films obtained by polymerization of each monomer.
