Abstract

The invention relates to a cobalt phthalocyanine / copper phthalocyanine / pitch coke activated carbon catalytic material and method for preparing a lithium thionyl chloride battery positive plate by using the catalytic material. The method comprises the following steps of: taking pitch coke activated carbon with a large specific surface area (800m2 / g) and high activity as a template, and growing cobalt phthalocyanine and copper phthalocyanine on the surface in situ, wherein a pitch coke activated carbon framework plays a role in structural support, and is linked through hydrogen bonds and covalent bonds, so that agglomeration of phthalocyanine complexes is avoided, and the structural stability of the material is improved; in addition, the preparation process is simple and easy to control through a solid-phase in-situ one-step sintering method, the period is short, the energy consumption is low, the repeatability of the product is high, the yield is high, and the large-scale production isfacilitated. The catalytic material prepared by the method is used for the lithium thionyl chloride battery, the initial discharge voltage is increased by 0.18V and the energy density is increased by73% compared with the initial discharge voltage of the anode material without the catalytic material. The application prospect is wide.
