Iron Compounds Preparation TRIZ Cases
- Iron Sodium Hydroxysulphide Anode Material for Swelling-Resistant Na-Ion Cells
A lamellar iron sodium hydroxysulphide anode improves sodium mobility and conductivity while limiting swelling and mechanical ageing.
- Controlled-pH Iron Oxyhydroxide Precipitation for High Purity
Controlled precipitation at pH 6–10, Fe(II) oxidation, and demineralized-water washing reduce sodium, sulfur, chloride, and residual impurities.
