Liovix® Printable Lithium Technology for Controlled and Scalable Prelithiation of Silicon Anodes

Abstract

Loss of active lithium in the first cycle permanently lowers the lithium-ion cell energy density. Prelithiation employs an external, sacrificial source of lithium to offset these losses allowing more efficient use of lithium from the cathode and raising the cell energy density.LIOVIX®printable lithium technology is comprised of stabilized lithium metal powder (SLMP®) dispersed in a compatible solvent along with other rheology and performance modifiers to create a formulation that is chemically stable and not prone to separation for extended periods of time. The technology is easily scalable using industry standard coating and printing equipment to apply the formulation to the surface of a prefabricated anode. LIOVIX® can be used in anodes with a range of silicon content, because lithium loading can be accurately controlled based on the applications’ requirements.In this presentation, we will compare LIOVIX® to other prelithiation methods. The electrochemical results will be discussed as well.
