The advanced applications of ionic liquids in new energy, electronic information materials, and biotechnologies

Ionic liquids (ILs) with remarkable performance offer opportunities to advance green and low-carbon chemical processes. Thus, much work is focused on building an innovative theory and knowledge framework to unravel the nature of ILs. Moreover, there is an increasing trend to utilize ILs in rapidly emerging fields. Aiming to provide an overview of the recent advances and challenges of ILs in the development of green processes for renewable resources, this review highlights the properties and functions of ILs in IL gating and as electrolyte additives, modifiers, exfoliation agents, nucleation substrates, tunable solvents, versatile carriers and biosensor components in three representative and revolutionary production processes, namely, new energy, electronic information materials, and biotechnologies. The innovative applications of ILs demonstrate their potential to create a landscape of low-carbon, high-end and smart technologies.
