摘要:
A rechargeable lithium cell comprising: (a) an anode comprising a prelithiated lithium storage material or a combination of a lithium storage material and a lithium ion source; (b) a hybrid cathode active material composed of a meso-porous structure of a carbon, graphite, metal, or conductive polymer and a phthalocyanine compound, wherein the meso-porous structure is in an amount of from 1% to 99% by weight based on the total weight of the meso-porous structure and the phthalocyanine combined, and wherein the meso-porous structure has a pore with a size from 2 nm to 50 nm to accommodate phthalocyanine compound therein; and (c) an electrolyte or electrolyte/separator assembly. This secondary cell exhibits a long cycle life and the best cathode specific capacity and best cell-level specific energy of all rechargeable lithium-ion cells ever reported.
