Impact of Anion Mixing on Li + Coordination and Transport Properties in Pyrrolidinium-Based Ionic Liquid Electrolytes

Key Points

• The research aims to determine how mixed anions affect lithium coordination and transport properties in pyrrolidinium-based ionic liquids.
• Investigated a series of pyrrolidinium-based ionic liquid electrolytes.
• Explored the effects of mixed anions (bis(fluorosulfonyl)imide and bis(trifluoromethylsulfonyl)imide).
• Mixed anion electrolytes showed improved lithium ion transport properties.
• Enhanced coordination dynamics were observed with the incorporation of bis(fluorosulfonyl)imide.
