The electrodeposition of composite electrochemical coatings (CECs) based on the nickel–cobalt alloy attracts interest because of high performance characteristics of the coating, such as wear resistance, microhardness, and corrosion resistance [1–4].In these characteristics, CECs based on the nickel–cobalt alloy [4, 5] can replace chromium coatings that are …
Li(Ni 0.8 Co 0.1 Mn 0.1)O 2 (NCM811) was synthesized using alkali chlorides as a flux and the performance as a cathode material for lithium ion batteries was examined. Primary particles of the powder were segregated and grown separately in the presence of liquid state fluxes, which induced each particle to be composed of one primary particle with well-developed facet …

Nickel is another metal essential to the design of rechargeable batteries, and is the fifth most abundant element on earth. It is the most important metal by mass in the cathode of a lithium-ion battery, accounting for up to 80% cathode weight in nickel-cobalt-aluminium cathodes ("NCA") or in some nickel-manganese-cobalt ("NMC") cathodes.
The activation energies for the thermal decomposition of metal oxalate comprising nickel are in the range of 1.21 × 10 5 –1.69 × 10 5 J/mol [47].Previous studies on the thermal decomposition of nickel oxalate and cobalt oxalate indicate that its favorable decomposition temperature is above 350 ºC [48], [49].In view of this, the obtained nickel-cobalt oxalate …
In this paper, Cyanex272 was employed to extraction and separation of nickel and cobalt. Acetic acid solution was used to reverse extract cobalt from the organic phase, and the …
Restenosis of intracoronary stents is discussed separately. ... (ACD) caused by nickel. Cobalt, chromium, molybdenum, and gold are less often implicated in ACD .

The selective separation of cobalt from nickel is of major importance for the recovery of cobalt from primary or secondary sources, as well as for analytical purposes.
Nickel:cobalt ratios greater than 500:1 were obtained when the cathode and anode current densities were equal and approximately 1 ampere per square decimeter. Nickel containing an average of 0.4 percent cobalt was obtained for 549 ampere-hours of operation, after which the 1-percent-cobalt limit was exceeded. ... These two ideas were used ...

In Australia, there are a number of nickel HPAL projects in the pipeline, the most advanced being Clean Teq's Sunrise nickel-cobalt-scandium project in New South Wales, where a definitive feasibility study was ...
The second principle of ferronickel smelting is that laterite ores cannot be smelted to nickel metal alone, i.e., separately from iron. This is because (1) garnierite concentrates always contain 5–10 times more Fe than Ni and (2) oxygen is only slightly more strongly bonded to Fe than to Ni—i.e., FeO in calcined concentrate is almost as ...
