The Technology
In Li-ion batteries electrode materials degrade through their reactive interface with the electrolyte. The undesirable interfacial reactions result in formation of layers that impede charge transfer and can serve as an active site for electrolytic consumption, electrode corrosion and passivation, thereby, leading to inefficient lithium ion batteries.
Stabilizing the electrode interface by creating an artificial protection layer can significantly enhance the battery performance by stabilizing the functional interphase and by significantly reducing the undesirable parasitic reactions. This is achieved by molecular/atomic layer deposition (M/ALD)of thin, ion conductive and electronically insulating multifunctional film.
This research is conducted in collaboration with Prof. Malachi Noked in Bar-Ilan University.
