Synthesis of polypyrrole and electrochemical performance of dual-ion battery

Conducting DBSA-PPy was fabricated by reverse microemulsion polymerization. DBSA increase the conductivity of PPy when it is used as the dopant and was surfactant, since the W/O microemulsion can supply nano-reactor. The electrochemical performance of dual ion battery with graphite as the anode and DBSA-PPy as the cathode materials was tested, the result shows that the battery has as good electrochemical characteristics as traditional lithium-ion battery, due to the high conductivity and doped structure of the prepared DBSA-PPy, which indicates that conducting polymer as positive materials of electrode is hopeful for the application.
