Estimating the term…
There is provided a polyaniline having a thickness of 0.3 to 5 mm which is suitable for an electronic material, particularly for an electrode material in a cell. Also provided is a cell comprising a positive electrode, a negative electrode and an electrolyte in which the polyaniline having a thickness of 0.3 to 5 mm is employed in at least one of the positive and negative electrodes, the cell having a high energy density and good cell performance stable for a long period of time.
A polyaniline film having a thickness of 0.3 to 5 mm and a density of 0.4 to 1.1 g/cm.sup.3.
A polyaniline film having a thickness of 0.3 to 5 mm and a density of 0.4 to 1.1 g/cm.sup.3 which is prepared by the process comprising electrochemically polymerizing aniline in an electrolytic solution containing aniline and borofluoric acid to form said polyaniline film and then pressing the thus formed polyaniline.
A polyaniline film having a fibrous structure comprising polyaniline fibers randomly tangled with each other and characterized by a bulk density of from 0.4 to 1.1 g/cm.sup.3.
