Solid-state electrolyte for lithium-metal anode in electrochemical cell
A recently granted patent (Publication Number: US11967676B2) discloses a novel catholyte solution for use in electrochemical cells. The solution comprises a lithium salt, sulfolane, and ethylene sulfite, with the ratio of sulfolane to ethylene sulfite ranging from 30:70 v/v to 50:50 v/v. Additionally, the catholyte solution may include additives such as 1,3-propane sultone and thiophene, as well as a solid-state electrolyte made of lithium-stuffed garnet in thin film form.
Furthermore, the patent outlines a method for producing the catholyte solution by mixing sulfolane and ethylene sulfite with a lithium salt. The solution's boiling point falls within the range of 60°C to 100°C, making it suitable for various electrochemical applications. Another aspect of the invention involves a catholyte solution containing a lithium salt and two C3-10 heterocyclic molecules, with sulfolane and ethylene sulfite being the preferred choices. The ratio of these heterocyclic molecules is maintained between 30:70 v/v to 50:50 v/v, highlighting the precise composition required for optimal performance in electrochemical cells.
