Abstract
A rechargeable lithium cell comprising: (a) an anode comprising an anode active material; (b) a cathode comprising a hybrid cathode active material composed of an electrically conductive substrate and a phthalocyanine compound chemically bonded to or immobilized by the conductive substrate, wherein the phthalocyanine compound is in an amount of from 1% to 99% by weight based on the total weight of the conductive substrate and the phthalocyanine compound combined; and (c) electrolyte or a combination of electrolyte and a porous separator, wherein the separator is disposed between the anode and the cathode and the electrolyte is in ionic contact with the anode and the cathode. This secondary cell exhibits a long cycle life, the best cathode specific capacity, and best cell-level specific energy of all rechargeable lithium-ion cells ever reported.
