▎ 摘　　要

NOVELTY - A rechargeable lithium cell comprises: an anode containing an anode active material, where the anode active material is a prelithiated lithium storage material or a combination of a lithium storage material and a lithium ion source; a cathode containing hybrid cathode active material composed of a graphene material and phthalocyanine compound; and a porous separator disposed between the anode and the cathode and electrolyte in ionic contact with the anode and the cathode. USE - As a rechargeable lithium cell (claimed), used in a rechargeable lithium metal battery. ADVANTAGE - The rechargeable lithium cell has a long charge-discharge cycle life (i.e. greater than 300 cycles, preferably greater than 500 cycles, and especially greater than 1000 cycles); has a high energy density. The incorporation of a graphene material in the cathode active material can significantly reduces the solubility and catalytic effect and in some cases has essentially eliminated these problems, in addition to providing good electrical and thermal conductivity to phthalocyanine, leading to a dramatically improved charge/discharge cycle life and long-term stability of a lithium cell. The co-existence of a phthalocyanine compound and a graphene material can bring out the best of the two cathode active materials, providing an unexpected synergistic effect to achieve a cathode specific capacity that cannot be achieved by either component alone. DETAILED DESCRIPTION - A rechargeable lithium cell comprises: an anode containing an anode active material, where the anode active material is a prelithiated lithium storage material or a combination of a lithium storage material and a lithium ion source selected from lithium metal, lithium alloy, or lithium-containing compound; a cathode containing hybrid cathode active material composed of a graphene material and phthalocyanine compound, where the graphene material is in an amount of 0.1-99 wt.% based on the total weight of the graphene material and the phthalocyanine compound combined; and a porous separator disposed between the anode and the cathode and electrolyte in ionic contact with the anode and the cathode.
