摘要： A mesophase pitch-based carbon fiber for use as a material for a negative electrode of a secondary battery, and a process for producing the same. The mesophase pitch-based carbon fiber comprises a columnar core part having a texture composed of a plurality of graphite layers extending along an axial direction and extending with minute flexures in a plane perpendicular to the axis and an outer-shell part surrounding the core part. The outer-shell part has a texture composed of a laminate of a plurality of graphite layers extending along an axial direction. The graphite layers are oriented in a plane perpendicular to the axis in a fashion such that the graphite layers extend along a circumferential direction with minute flexures while gradually receding from a center of the core part. In the carbon fiber, the graphite layers composing the outer-shell part have a laminate face forming a surface of the outer-shell part, channels permitting entry and exit of lithium ions being formed between graphite layers at the laminate face.

摘要： There is disclosed a process for producing pitch-based carbon fiber which comprises melt spinning an optically isotropic pitch or a mesophase pitch to form pitch fiber; subjecting the pitch fiber to liquid-phase oxidative polymerization in a solvent e.g. acetic acid in the presence of an acid catalyst such as strong inorganic acids and a crosslinking selected from formalin, paraformaldehyde or tioxane agent to form infusibilized fiber; and carbonizing the infusiblized fiber. The above process enables low temperature and short time infusibilizing treatment of optically isotropic pitch fiber having a low softening point which has heretofore been difficult because of failure to preserve the original fibrous shape during infusibilization, and also efficient production of mesophase pitch-based carbon fibers as well as optically isotropic pitch-based carbon fibers each being improved in physical properties.
