Multiple regression analysis in the development of NiFe cells as energy storage solutions for intermittent power sources such as wind or solar

Multiple regression analysis was used to investigate the effect of bismuth sulphide and iron sulphide as anode additives for NiFe cells.

Summary:Multiple regression analysis was used to investigate the effect of bismuth sulphide and iron sulphide as anode additives for NiFe cells. With this in mind, in-house made Fe/FeS/Bi2S3 based electrodes were cycled against commercially available nickel electrodes. A simplex centroid design was used to investigate the combined effects of any of the aforementioned additives on cell performance. The manuscript ends with an initial look at electrolyte systems as a means to further improve the performance of our cells. Finally, our findings support the idea that HS- ions improve the overall performance of NiFe cells. [Display omitted] •We investigate selected electrode and electrolyte additives on cell performance.•Hydrogen evolution is linked to NiFe battery performance.•The performance of a NiFe Cell depends on the initial cycles of charge/discharge.
