Characteristics of Heat-treated PPP (Poly Para Phenylene) at 973K as an Anode of Lithium Battery

Abstract

PPP (Poly Para Phenylene) heat-treated at various temperatures was evaluated as an anode of Lithium secondary battery. The specimen heat-treated at 973K showed discharge capacity of 370Ah/kg, close to that of LiC₆, under the condition of 1.6mA/cm² current density and +10mV-3V (vs. Li/Li⁺) charge-discharge terminate voltage.
From the results of several analytical methods including X-ray diffraction and laser Raman spectroscopy, this specimen can be defined as an intermediate material between organic compounds and inorganic carbons. Thus present heat-treated PPP is quite attractive in the applications of Lithium secondary batteries.
