The time constant for the RC couple is assumed to be 15 s. The Battery Open Circuit Voltage node (OCV1) requires the battery open circuit voltage data, E OCV (V), as function of state-of-charge. Initial battery capacity and state-of-charge are also required as inputs for the Battery Open Circuit Voltage node.
The partial nickel current measurements have been limited to a maximum value of, less than 10% of the diffusion-limited current density. They are also situated at potentials sufficiently far away from the open-circuit values, given in Table IV, for the contribution from the anodic portion of the polarization curve to be neglected. The nickel ...

The purpose of this study is mainly to investigate the influence of surfactant in the electrolyte and the Sc-CO 2 assisted process in the nickel plating of the ENIG process, especially for blind via in PCB. Therefore, the PCB specimens with different sized via were employed in the experiment, as presented in Table 1.Nine via were configured in square …
The below shown NiCad charger circuit is developed to supply either 50mA to four 1.25V cells (type AA), or 250mA to four 1.25V cells (type C) connected in series, eventhough it could simply be modified for various other charging values. In the discussed NiCad charger circuit R1 and R2 fix the off-load output voltage to approximately 8V.

Figure 6 shows the staging of a typical Cyanex 272 circuit for cobalt –nickel separation, while Table 2 provides illustrative SX feed and LSL compositions . Comparison with the D2EHPA circuit (Fig. 3) demonstrates the remarkable simplification (and capital cost savings) possible with this new-generation reagent.
The dilute nickel concentration in the scrub raffinate resulted in a wash efficiency of 90%. Overall nickel removal from the loaded organic was therefore 87%, resulting in a CoSX nickel extraction of 0.02%. Despite encouraging performance from the scrub circuit, Co:Ni on the scrubbed organic remained well below the target of 700.
