Abstract
A solid film was prepared by electrodepositing on a gold-film-coated quartz crystal electrode in Na2FeO4 solution, and characterized in 1 M LiClO4/propylene carbonate (PC) + 1, 2-dimethoxyethane (DME; 1:1 by volume) electrolyte using electrochemical quartz crystal microbalance (EQCM). The EQCM experimental and X-ray photoelectron spectroscopy results indicate that the composition of the electrodeposited solid film prepared in the potential range of 0.18 to −0.57 V vs. Ag/AgCl is FeOOH; and almost 1 mol lithium ions can be intercalated into and then extracted from 1 mol FeOOH film during discharge/charge process in 1 M LiClO4/PC + DME electrolyte. The discharge/charge experiment indicates that the specific capacity of FeOOH film stabilizes at a value close to its theoretical specific capacity after 20 cycles, and FeOOH film maintains a specific capacity of about 300 mAh g−1 at the end of 170 cycles. It is therefore concluded that the FeOOH film has a good electrochemical cycle ability in 1 M LiClO4/PC + DME electrolyte.
