Mechanics of electrochemically coprecipitated cobalt

An investigation into the effects of adding cobalt hydroxide to nickel hydroxide electrodes has provided some insight as to why cobalt is an effective additive. The investigative techniques emphasized in situ measurements of electrode mechanical behavior rather than electrochemical data as employed

Microelectrode Studies of Electrochemically Coprecipitated

09/12/2019· In general, the presence of coprecipitated cobalt hydroxide appears to render the charge‐discharge reaction more reversible thereby allowing charging to occur at less positive potentials, this apparently increases the charging efficiency by minimizing concurrent oxygen evolution. The microelectrode was also used to characterize the cathodic deposition process for the nickel hydroxide.

Simultaneous coprecipitation of lead, cobalt, copper

A simple and new coprecipitation procedure is developed for the determination of trace quantities of heavy metals (lead, cobalt, copper, cadmium, iron and nickel) in natural water and food samples. Analyte ions were coprecipitated by using zirconium(IV) hydroxide. The determination of metal levels was performed by flame atomic absorption spectrometry (FAAS). The influences of analytical

In Situ Monitoring of the Growth of Nickel, Manganese,

27/09/2018· In this paper, the evolution of nickel, manganese, and cobalt hydroxide precursor, Ni 1/3 Mn 1/3 Co 1/3 (OH) 2, is investigated using a combination of in situ and ex situ techniques during the commonly-used coprecipitation process. These include in situ wide angle X-ray scattering, in-situ ultra-small angle X-ray scattering and ex situ particle size analysis. The growth rate of crystalline Ni

High density cobalt-manganese coprecipitated nickel

The present invention provides high density cobalt-manganese coprecipitated nickel hydroxide, particularly having a tapping density of 1.5 g/cc or greater, and a process for its production characterized by continuous supply of an aqueous solution of a nickel salt which contains a cobalt salt and a manganese salt, of a complexing agent and of an alkali metal hydroxide, into a reactor either in

The leaching kinetics of cobalt and nickel from aluminum

The leaching behavior of cobalt and nickel from aluminum-coprecipitated products in ammoniacal solutions has been investigated. Cobalt and nickel were precipitated with aluminum in a solution containing 0.5 M of total ammonia, a mixture of ammonium hydroxide and ammonium nitrate at pH 10. The leaching was carried out at 2 M total ammonia concentration at pH 10.

PROCESS FOR NICKEL-COBALT SEPARATION TUNIS L.

Sodium hydroxide was added to this solution until the pH increased to 8.0 at which point the dissolved nickel plus cobalt was coprecipitated as nickel/cobalt hydroxide. This precipitate, containing approximately 5 grams of nickel plus 5 grams of cobalt, was filtered from the solution and air dried for 72 hours. The dried mass was gradually added to approximately 500 grams of commercially pure sodium

A New Process for Cobalt Nickel Separation

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching. This combination of flotation and smelting effectively
