    摘要: A method for converting amorphous carbon fiber to graphitized carbon fiber, the method comprising immersing the amorphous carbon fiber into a molten anhydrous alkaline earth salt (e.g., CaCl2) and/or MgCl2) maintained at a temperature within a range of 720° C.-920° C. or 780° C.-920° C. while the amorphous carbon fiber is cathodically polarized at a voltage within a range of −2.2V to −2.8V for a period of time (e.g., 0.5-6 hours) to result in conversion of the amorphous carbon fiber to the graphitized carbon fiber, wherein the graphitized carbon fiber is at least partially graphitized.
