The reductive and oxidative intercalation of ions into graphite from room-temperature and low temperature molten salts is demonstrated. For this investigation, the molten salts use 1-ethyl-3-methylimidazolium (EMI[sup +]) or 1,2-dimethyl-3-propylimidazolium (DMPI[sup +]) as the cation and AlCl[sup [minus]][sub 4], BF[sup [minus]][sub 4], PF[sup [minus]][sub 6], CF[sub 3]SO[sup [minus]][sub 3], or C[sub 6]H[sub 5]CO[sup [minus]][sub 2] as the anion. In a two-electrode battery configuration, the molten salt electrolyte provides both the cation and anion which are intercalated into the graphite anode and cathode, respectively. A cell employing a (DMPI)(AlCl[sub 4]) electrolyte and two graphite rod electrodes achieved an open-circuit voltage of 3.5 V and a cycling efficiency of 85%.
