Case Study

The Potential of Zinc Sulfide as An Additive for the Preparation of High-Performance Iron Electrodes

Mitra, D., et al. Journal of The Electrochemical Society, 2021, 168(3), 030518.

In iron-based alkaline rechargeable batteries, sulfide additives have been shown to overcome the limitations of low charging efficiency and poor discharge rate capability of iron electrodes. The effect on iron electrodes was compared with iron (II) sulfide, iron (II) disulfide, copper (I) sulfide, and zinc sulfide, with the electrode containing zinc sulfide showing the best performance. The electrode has a remarkable Faradaic efficiency of 95% at C/2 rate, a specific discharge capacity of nearly 0.24 Ah·g-1 at 1 C rate, and can stably repeat deep discharge for 750 cycles.
Preparation procedure of zinc sulfide-iron electrode
· First, the powder mixture consisted of 70 w/w% carbonyl iron, 10 w/w% potassium carbonate, 5 w/w% zinc sulfide, 10 w/w% bismuth oxide, and 5 w/w% polyethylene binder.
· The powder mixture was then hot-pressed onto a clean (degreased) nickel mesh at 140 °C and a pressure of 15 kg cm-2 to prepare the electrode.
· Subsequently, electrochemical measurements were performed in a three-electrode polypropylene cell with a mercury/mercury oxide (MMO) reference electrode and a nickel mesh counter electrode.
