The present invention concerns a three dimensional conductive organic polymer covered micro structure having improved current carrying capacity as compared to a substantially smooth surface. More specifically, it relates to a three-dimensional poly(aniline) or poly(pyrrole)-substrate micro structure for use as a battery electrode, having improved properties as compared to a substantially smooth surface, which structure comprises: a thin surface layer of poly(aniline) or poly(pyrrole) film on a substrate surface, wherein the polyaniline or poly(pyrrole) film has a thickness of between about 0.1 and 10 microns and the substrate surface is irregular or patterned having a protruding surface, wherein representative protrusions amount to between about 40 to 90 percent of the surface of the electrode. The processes to produce the three-dimensional microstructure are also disclosed.
A three dimensional electrically conductive organic polymer covered structure having multiple surface microprotrusions and improved current carrying capacity as compared to a substantially smooth surface;
The structure of claim 2 which reversibly charged at between about 5 and 15 milliampere per square centimeter.
A three-dimensional polymer structure for use as a battery electrode, having improved current carrying capacity and reversible charging properties as compared to a substantially smooth polymer surface, which structure comprises:
A three-dimensional organic electrically conducting polymeric battery electrode having multiple microprotrusions obtained by a process to produce the three-dimensional microstructure surface device, which is useful as a battery electrode, which process comprises:
