中文摘要	kpf6 dissolved in propylene carbonate (pc) has been proposed as an electrolyte for activated carbon (ac)/graphite capacitors. the electrochemical performance of ac/graphite capacitor has been tested in xpf6-pc or xbf4-pc electrolytes (x stands for alkali or quaternary alkyl ammonium cations). the ac/graphite capacitor using kpf6-pc electrolyte shows an excellent cycle-ability compared with other electrolytes containing alkali ions. the big decomposition of the pc solvent at the ac negative electrode is considerably suppressed in the case of kpf6-pc, which fact has been correlated with the mild solvation of k+ by pc solvent. the relationship between the ionic radius of cation and the corresponding specific capacitance of ac negative electrode also proves that pc-solvated k+ ions are adsorbed on ac electrode instead of naked k+ ions.
