Intercalation of PF_(6)~(-) Anion into Nano Pore into Graphene Layer for Improved Capacity of Hybrid Capacitor

摘要

High performance electric source is critically requested at present for the improvement of the performance of mobile equipments. In this study, intercalation property of PF_(6)~(-) into graphitic carbon was studied and it was found that introduction of nano size pore into graphene sheet resulting in a large capacity for intercalation capacity of 147 mAh/g. The estimated energy density of the cell using carbon with nano porous structure was ca. 400 Wh/kg.
