Abstract

The invention belongs to the technical field of storage batteries, and concretely discloses conductive carbon fiber. The conductive carbon fiber comprises a core material and a coating which is coatedon the surface of the core material; the core material is carbon fiber, and the coating comprises the following materials in parts by mass: 87-91 parts of a zinc alloy coating material, 2-4 parts ofan anti-oxidant, 3-5 parts of polypropylene, and 0.5-1.5 parts of graphite fiber. The zinc alloy coating material comprises the following raw materials in parts by mass: 0.1-0.5 parts of aluminium, indium, gallium, thallium, magnesium, calcium, strontium, cadmium and tin, 0.5-2 parts of bismuth, and 95-98 parts of zinc. Compared with the prior art, the conductive carbon fiber does not contain lead, and can inhibit generation of hydrogen from reaction of zinc and active substances during battery usage process, so that safety performance of the battery is guaranteed, and usage life of the battery is prolonged.
