“…Swelling reduces the integrity of the electrodes and causes a bad electrical contact between the active material and substrate. Consequently, the electrode performances are impaired by the decrease in the charging efficiency and cycle life of the electrodes [26,27]. Swelling, as reflected by an increase in the thickness of the electrodes, is related to the formation of c-NiOOH during cycling.…”

Nickel hydroxide powder was modified by the method of ball milling, and the physical properties of both the ball-milled and un-milled nickel hydroxide were characterized by scanning electron microscopy, specific surface area, particle size distribution and X-ray diffraction. It was found that the ball milling processing could obviously increase the surface area, decrease the particle and crystallite size, and reduce the crystallinity of b-Ni(OH) 2 , which was advantageous to the improvement of the electrochemical activity of nickel hydroxide powder. Electrochemical performances of pasted nickel electrodes using the ball-milled nickel hydroxide as an active material were investigated, and were compared with those of the electrodes prepared with the un-milled nickel hydroxide. Charge/ discharge tests showed that the ball-milled nickel hydroxide electrodes exhibited better performances in the charging efficiency, specific discharge capacity, active material utilization and discharge voltage. The improvement of the performances of b-Ni(OH) 2 through ball milling could be attributed to the better reaction reversibility, higher coulombic efficiency, higher oxygen evolution potential and lower electrochemical impedance, as indicated by the cyclic voltammetry and electrochemical impedance spectroscopy studies. Thus, ball milling was an effective method to modify the physical properties and enhance the electrochemical performances of nickel hydroxide powder for the active material of rechargeable alkaline nickel batteries.

“…NieCo/glassy carbon electrode had a higher activity towards methanol oxidation in Ni(III) and Co(IV) oxidation states [11]. Oshitani et al [12,13] have concluded that the addition of Co(OH) 2 could increase the charge-acceptance of nickel electrodes and prevents the formation of another form of nickel oxyhydroxide [g-NiOOH] that can result in the swelling of nickel electrode. Sun et al [14] have prepared NieCo hydroxide electrodes by coelectrodeposition on stainless steel mesh.…”

“…(1) is followed by the oxygen evolution reaction in Eq. (2). Because the oxygen overpotential of nickel electrode drops rapidly in the high-temperature range of over 35 • C, the charging reaction and the oxygen evolution reaction occur in conflict with one another, thereby it causes the charge efficiency to decrease.…”
