摘要： In a method of making a carbon fiber, PAN (poly(acrylonitrile-co methacrylic acid)) is dissolved into a solvent to form a PAN solution. The PAN solution is extruded through a spinneret, thereby generating at least one precursor fiber. The precursor fiber is passed through a cold gelation medium, thereby causing the precursor fiber to gel. The precursor fiber is drawn to a predetermined draw ratio. The precursor fiber is continuously stabilized to form a stabilized fiber. The stabilized fiber is continuously carbonized thereby generating the carbon fiber. The carbon fiber is wound onto a spool. A carbon fiber has a fiber tensile strength in a range of 5.5 GPa to 5.83 GPa. The carbon fiber has a fiber tensile modulus in a range of 350 GPa to 375 GPa. The carbon fiber also has an effective diameter in a range of 5.1 μm to 5.2 μm.

摘要： Provided is a binder composition for an electrochemical device electrode with which it is possible to form an electrode mixed material layer that has excellent peel strength and dusting resistance and that can cause an electrochemical device to display excellent rate characteristics. The binder composition for an electrochemical device electrode contains a binder and an organic solvent. The binder includes a particulate polymer A and a polymer B. The particulate polymer A has a core-shell structure including a core portion and a shell portion at least partially covering an outer surface of the core portion, and a polymer forming the shell portion has a glass-transition temperature of −50° C. to 20° C. A mixture obtained by mixing the polymer B in a concentration of 8 mass % with the organic solvent has a viscosity at a shear rate of 1 s−1 of 100 mPa·s to 10,000 mPa·s.
