Abstract: Ionic liquids of excellent lubrication performance have aroused widespread concern. This paper reviewed recent progress on the tribology properties and conductive capacity of the ionic liquids. The conductive capacity and tribology properties of ionic liquids as additive in lubricating grease have been focused on. Based on the above cognition, the unsolved problems and the future research trend of the ionic liquids as the conductive additive in lubricating grease were forwarded.
