Abstract
Disclosed is an electrode material comprising a phthalocyanine compound encapsulated by a protective material, preferably in a core-shell structure with a phthalocyanine compound core and a protective material shell. Also disclosed is a rechargeable lithium cell comprising: (a) an anode; (b) a cathode comprising an encapsulated or protected phthalocyanine compound as a cathode active material; and (c) a porous separator disposed between the anode and the cathode and/or an electrolyte 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.
