Abstract

The effects of fluoride ions scavenger in the liquid phase deposition synthesis of nickel-aluminum layered double hydroxide/carbon (Ni-Al LDH/C) composite have been investigated. Al(NO3)3.9H2O, AlCl3, Al metal plate, and a mixed solution of [Al(NO3)3.9H2O and H3BO3] were employed as F- scavengers. In the case that Al material is solely used as F- scavenger, α-nickel hydroxide is the predominant phase, and a small amount of β-phase is detected. In contrast pure phase Ni-Al LDH/C composites, isostructural and isomorphic to α-Ni(OH)2 are obtained when a mixed solution of Al(NO3)3.9H2O and H3BO3 is used at any range of Al content. High purity LDHs without cationic species exhibited good stability in 6M KOH for 7 days. Short-term charge-discharge measurements at 1C-rate for the electrodes containing 0, 13.6 and 17.8 Al mol % showed an increase of the discharge capacity with increasing Al content.
