| Abstract: | The method to evaluate the reversible lithium insertion capacity (Qre) has been studied using poly (p-phenylence) (PPP) heat-treated at 550 1000 ℃ in inert gas atomsphere by H/C atomic ratio and FTIR measures. The H/C atomic ratio and Qre decreased with increasing heat-treament temperature. The absorption ratio of 1020cm-1 band to the 1440cm-1 band (Ra) is directly related to the Qre of carbon samples. The samples with R. >1-1 and without 807cm-1 peak tend to have high Qre (>372 mA.h-g-1). The reversible capacity for Li+ ion insertion decrease as Ra decreases. |
