Mesophase pitch based carbon fiber (MPCF)

Mesophase pitch based carbon fiber (MPCF)

Mesophase pitch based carbon fiber is a special fiber made of mesophase pitch through melting spinning, pre oxidation, carbonization, graphitization and other processes. High thermal conductivity carbon fiber is a high thermal conductivity carbon fiber material developed for thermal design. The thermal conductivity of this carbon fiber in the fiber direction can exceed copper, up to 400W / MK, and has good mechanical properties Electrical conductivity and excellent heat conduction, radiation and heat dissipation. Mesophase pitch as a graphitized carbon material, after high temperature treatment, is conducive to the transformation to crystalline graphite structure and form a regular three-dimensional stacking structure. This structure can be used to prepare electrode materials because of its low energy of lithium ion embedding, deep lithium embedding and improving reversible capacity. After surface modification, mesophase pitch was used as lithium ion electrode material to obtain carbon electrode with high charge discharge capacity and good cycle performance; Using petroleum mesophase pitch after carbonization and graphitization as cathode material of lithium ion battery, the performance can be compared with mesophase carbon microspheres.
