Abstract:

A novel hydrothermal stripping technique synthesis route, in which the nickel-loaded organic phase of naphthenic acid was directly stripped by water at 140-240 °C for 2.0 h to recover nickel as hydroxide precipitates, has been firstly developed. The nickel hydroxide powders synthesized by this route was the spherical β-Ni(OH)2 and had a small particle size in the range of 20-100 nm shown by XRD and TEM test. The results of electrochemical performances show that the nanometer β-Ni(OH)2 cathode materials have much higher discharge specific capacity, excellent capacity retention and cycle performances.
