Pulse-Current Electrodeposition for Loading Active Material on Nickel Electrodes for Rechargeable Batteries

Abstract

Although the pulse-current electrodeposition method is a commonly used technique, it has not been widely employed in electrode preparation. This method was applied to sintered nickel electrodes in a nickel salt solution containing additives. The active material that was obtained, nickel hydroxide, was studied using different characterization techniques. Electrodes impregnated with pulse current had higher capacity than those impregnated with continuous current. The active material is homogeneous and compact with optimum loading and good performance during discharge. These characteristics would provide a large amount of energy in a short time due to an increase in the electrode kinetic reaction.

Definition of the influence of pulsed deposition modes on the electrochromic properties of Ni(OH)2-polyvinyl alcohol films

“…It was also shown that nickel hydroxide formed on electrodes for alkaline batteries in a pulsed mode showed higher specific characteristics than those of hydroxide deposited in a DC mode [22].…”

Electrochemical studies on electrolytic preparation of battery grade nickel hydroxide – Effect of (OH)− to Ni2+ ratio

“…From Fig 3, E a (rest potential of anode) gives a slope of À0.044 against pH which may be considered a reasonable match with the value of À0.059 in Eq. (9). These observations need further qualification based on several premises with respect to the nature of reactions influencing the measured rest potential.…”
