Title:

ANODES FOR LITHIUM-BASED ENERGY STORAGE DEVICES

Document Type and Number:

WIPO Patent Application WO/2024/058845

Kind Code:

A3

Abstract:

An anode for an energy storage device includes an electrically conductive layer and a surface layer disposed over the electrically conductive layer. The current collector surface may be characterized by a plurality of grooves. A lithium storage layer overlays the surface layer. The lithium storage layer is characterized by a first average thickness and may include at least 40 atomic % silicon, germanium, or a combination thereof. In at least one lateral dimension, the grooves may be spaced apart by an average spacing distance that is 0.4 to 50 times the first average thickness.
