摘要	The Mn-substituted Ni(OH)(2) samples were prepared by a coprecipitation method, and their structure was characterized by X-ray diffraction (XRD). Their electrochemical performance was also investigated by various electrochemical techniques. The results of XRD indicated that the Ni(OH)(2) samples with Mn contents less than 20% mainly consist of beta-phase, and the sample with a pure a structure can be obtained when the Mn content reaches 28.3%. The results of the electrochemical experiments showed that the Mn-substituted Ni(OH)(2) samples manifest high electrochemical cycling stability, and the samples with lower manganese contents exhibit larger discharge capacity and higher discharge potential. It was also found that the doping of Mn obviously increases the oxygen evolution potential and leads to the formation of proton deficiency.
