Abstract: A quad-polymer composition includes monomers of (a) acrylonitrile, (a) vinylimidazole, (c) methyl acrylate and (d) either acrylic acid or itaconic acid. Such quad-polymer compositions may be used to form fibers (such as by melt spinning) that may then be annealed, stabilized, and/or carbonized to produce carbon fibers. The quad-polymer composition may be used for supercapacitors, lithium battery electrodes once carbonized, and as synthesized, it may be used for wound healing fibers, fabrics, coatings, and films, and anti-bacterial/anti-microbial fibers, fabrics, coatings and films. The carbon fibers formed from the quad-polymer composition may be used for the fiber composites for automobile, aerospace structures, marine structures, military equipment/parts, sporting goods, robotics, furniture, and electronic parts.

Abstract: A method of preparing a hard carbon-based electrode active material having high specific surface area by carbonization process control, comprises charging polyurethane into a high temperature furnace, supplying oxygen gas to the high temperature furnace and oxidizing the polyurethane under an oxygen atmosphere, supplying a nitrogen gas to the high temperature furnace and heating to carbonize a stabilized polyurethane under a nitrogen atmosphere, thereby producing a hard carbon, heating the hard carbon under a nitrogen atmosphere and supplying steam to activate the hard carbon under a steam atmosphere, thereby producing an active carbon, supplying hydrogen and reducing the active carbon under a hydrogen atmosphere, and cooling the active carbon under a nitrogen atmosphere.
