FIRST ELECTROCHEMICAL INTERCALATION OF LITHIUM INTO FULLERENATED POLY(N-VINYLCARBAZOLE)

Lithium batteries are attractive for energy storage because of their h igh theoretical energy densities. A mechanism of an electrochemical in tercalation reaction is suggested for the discharge of the first Li-fu llerenated poly(N-vinylcarbazole) battery on the basis of experimental data obtained from cyclic voltammetry, FTIR, XRD, and ESR. The above battery has a higher open-circuit voltage (ca. 3.2 V), and its dischar ge may be ascribed to the electrochemical intercalation process of lit hium in fullerenated poly(N-vinylcarbazole) for positive electrode mat erials. The effect of the discharge of the electric cell on the struct ure and paramagnetic property of fullerenated poly(N-vinylcarbazole) i s discussed. (C) 1996 John Wiley & Sons, Inc.
