摘要：

Raman spectroscopy was used to characterize the structural development of polyparaphenylene (PPP) based carbon at various heat treatment temperatures (T-HT), with an emphasis on the low T-HT regime. Experimental data show that PPP-based carbons undergo a smooth transiiton from a mostly PPP polymer-type structure for heat treatments below similar to 750 degrees C to a graphitized structure at a heat treatment temperature of 2700 degrees C. These results give insight into the unusually high specific capacities observed in lithium-PPP systems which are of particular interest for application to Li ion battery technology.
