摘要： Pyrolysis (carbonization) of various plastics, including recycled plastic, can generate carbonaceous materials cheaply and in bulk, which can then be converted into energy storage device materials, e.g., carbon anode active material for Li-ion batteries. The plastic can be dissolved in a suitable solvent or acid, or can be melted. Once liquefied it can be loaded into vessels for extrusion via an electrospinner. Polymer fibers may be formed from the liquefied plastic on the nano- and micro scales, and collected on a substrate, forming a fabric. These fibers can be converted to high purity carbon and used as electrode materials in batteries and supercapacitors. The fibers can also be coated with Ppy prior to pyrolysis; this helps fibers retain their morphology during carbonization. The fibers can also be loaded with additive particles to enhance their electrochemical performance or alter the composite properties.

摘要： The object of the present invention is to realize a separator that has excellent thermal stability in size, shape, and the like even in a high temperature environment. The separator comprises a nonwoven fabric obtained by subjecting a nonwoven fabric consisting of homo-PAN fibers to a flame proofing treatment in a temperature range of 210° C. to 300° C., wherein an ID/IN value, which is a ratio of an absorption peak intensity ID of a carbon double bond-derived region (1580-1610 cm−1) of the homo-PAN nonwoven fabric to an absorption peak intensity IN derived from a nitrile group (2240 cm−1), as determined by infrared absorption spectroscopy, is 0.07 or more; and wherein a fiber shape and size are stably maintained after immersion for 30 minutes in an electrolytic solution containing propylene carbonate at 140° C.

摘要： Organized materials on a substrate. The organized materials are monolayer(s) of close-packed nanoparticles and/or microparticles. The organized materials can be formed by transfer of one or more monolayers to a substrate from a coating composition on which a monolayer of close-packed nanoparticles and/or microparticles is formed. Organized materials on a substrate can be used in devices such as, for example, batteries, capacitors, and wearable electronics.
