Description

General description

Sodium molybdate is a white powder that is an environmentally friendly non-oxidizing corrosion inhibitor and Mo source which is widely used in rechargeable batteries and supercapacitors.

Application

Sodium molybdate can be used as:

• A precursor to prepare MoS₂-based electrode materials for sodium-ion batteries with high initial Coulombic efficiency (ICE), high-rate performance, and long cycle life.
• An electrolyte additive in energy storage devices such as supercapacitors, to prevent the corrosion of stainless-steel collectors and enhance the performance.
• A source of molybdenum to synthesize MoS₂ quantum dots that can be used in fluorescence sensors for ascorbic acid detection.
