Abstract
Li_ion secondary batteries negative electrodes were prepared by low temperature (<1 000 ℃) pyrolysis of commercial phenol_formaldhyde resin. A thermogravimetric analysis (TGA) and an X_ray diffraction (XRD) studies were peoformed for the pyrolytic carbonaceous materials. The results indicated that these samples are amorphous polyacenic structure materials. With increasing pyrolytic temperature, these materials become structurally order, and the first charge_discharge special capacities reduce. The specific capacities base on pyrolytic temperature, involving lithium storage nanometer cavities.
