Nanosized nickel hydroxide powder for alkine batteries was synthesized in aqueous or nonaqueous solution of nickel chloride with NaOH under ultrasound radiation at the multibubble sonoluminescence (MBSL) condition. Characterization by X-ray diffraction, transmission electron microscopy, FT-IR spectroscopy, as well as elemental analysis indicates the formation of β<SUB>bc</SUB>-type nickel hydroxide. The β<SUB>bc</SUB>-type nickel hydroxide synthesized in aqueous solution of NiCl₂ is slightly different that formed in nonaqueous solution of NiCl₂. The synthetic process of β<SUB>bc</SUB>-type nickel hydroxide at the MBSL condition was completed within 5 minutes. Coating of nickel hydroxide particles on various oxide particles such as Al₂O₃ and SiO₂ was also prepared at the MBSL condition.
