Comparison of lithium// polyaniline secondary batteries with different dopants of HCI and lithium ionic salts

摘要

Polyanilines doped either with a protonic acid (HCI) or an electrolytic solution containing a lithium ionic salt(LiPF_6 or LiBF_4) are prepared and their electrochemical characteristics for use as polymer electrodes of lithium secondary batteries are investigated. An emeraldine base (EB) film doped with HCI ha the highest d.c. conductivity (`10 S /cm). An EB-LiPF_6 film has higher coductivity (0.52 S/cm) than an EB-LiBF4 (`0.082 S /cm) film.
