When an electrolyte is injected into the porous electrodes of a lithium-ion battery, it rapidly fills the pores. The result is a medium that allows lithium ions to pass from one electrode to the other but does not conduct electrons. When lithium salts dissolve in a solvent, their crystalline structure fully disintegrates.
Improving battery performance requires the careful design of electrolytes. Now, high-performing lithium battery electrolytes can be produced from non-solvating solvents by using a molecular-docking solvation strategy that takes advantage of intermolecular interactions between solvents to precisely control the solvation dynamics of lithium ions.
However, recent progress in the development of advanced lithium batteries, particularly those designed for lithium metal anodes, has shifted the main focus of research towards developing electrolytes capable of sustaining a stable interface between the electrodes and electrolytes 3.
In advanced polymer-based solid-state lithium-ion batteries, gel polymer electrolytes have been used, which is a combination of both solid and polymeric electrolytes. The use of these electrolytes enhanced the battery performance and generated potential up to 5 V.
In the field of lithium battery recycling, some experts advocate for the use of green solvents known as DESs. These solvents can efficiently extract value from used lithium batteries as leaching or reducing agents, while significantly reducing the generation of pollutants during the recycling process.
Because of the polarity difference between the non-ionizing diluent and ionizing solvent, lithium salt and the ionizing solvent molecules aggregates to form the cluster-like solvation sheaths in the non-polar diluent.
