A New Configuration Of The Solid-state Battery: Magnesium|polymer Proton Conductor|gold, Based On The Use Of Poly(o-methoxyaniline)

A solid-state battery was constructed by interfacing a pressed pellet of poly(o-methoxyaniline), in the emeraldine form with p-toluene sulfonic acid as doping agent, to a magnesium electrode covered with a film of magnesium perchlorate; the contact on the poly(o-methoxyaniline) was done by means of a gold electrode. The so-obtained cell, Mg|magnesium perchlorate|poly(o-methoxyaniline)|gold, was able to supply energy with a power depending on discharge current and on environmental humidity. Values of power up to 2.5 mW cm-2 at discharge currents of about 2 mA cm-2 were reached. © 1997 Elsevier Science S.A.9013136Gemeay, A.H., Nishiyama, H., Kuwabata, S., Yoneyama, H., (1995) J.
