Usage of MoS₂

MoS₂ with particle sizes in the range of 0.1-40 µm is a common dry lubricant, offering high lubricity and stability up to 350°C. MoS₂ is also used in ski glide wax.

Molybdenum disulfide was also used in the first rechargeable lithium batteries which have been introduced in the mid-1980s. The cell used lithium metal as the anode and MoS₂ on an aluminum foil as the cathode with LiAsF₆ as electrolyte. Due to the safety problems the batteries have been withdrawn from the market.

MoS₂ is used as a catalyst for desulfurization in petroleum refineries. The catalytic surface is generated in situ by applying H₂S to molybdate/cobalt or nickel-impregnated alumina.
