IN285739: A novel electrochemical process for bulk production of battery grade beta nickel hydroxide using consumable nickel anode
Abstract
The investigation suggests a process for the bulk preparation of battery grade beta nickel hydroxide electrochemically using nickel consumable anode. It is a low electricity consumption process as nickel dissolution potential is much lower than oxygen evolution reaction occurring at inert electrode during anodic process. The electrolytic efficiency for this process was close to 100%. The sample obtained in this process is highly crystalline beta nickel hydroxide conformed by the XRD analysis. The discharge capacity determination shows that the nickel hydroxide prepared by the above method has a higher discharge capacity which is suitable to battery industries. The nickel ion produced at the anode in place of oxygen evolution provides a better nickel ion-hydroxyl ion balance enhancing efficiency for beta nickel hydroxide production.
