Abstract
Systems and methods for anisotropic expansion of silicon-dominant anodes may include a cathode, an electrolyte, and an anode, where the anode may include a current collector and an active material on the current collector. An expansion of the anode during operation may be configured by a metal used for the current collector, and/or a lamination process that adheres the active material to the current collector. The expansion of the anode may be more anisotropic for thicker current collectors. A thicker current collector may be 10 μm thick or greater. The expansion of the anode may be more anisotropic for more rigid materials used for the current collector. A more rigid current collector may include nickel and a less rigid current collector may include copper. The expansion of the anode may be more anisotropic for a rougher surface current collector.
