Abstract:

A method and system for copper coated anode active material may include providing a metal current collector; an active material layer on the current collector, the active material layer comprising at least 50% silicon by weight, a pyrolyzed carbon source; and a layer of metal on the active material layer that increases conductivity of the layer. The surface may be opposite to a surface of the active material layer that is coupled to the current collector. The layer of metal may comprise copper. The silicon may comprise particles ranging in size from 2 to 50 μm. The metal layer may comprise islands of metal on the silicon particles. The islands of metal may have a thickness of 100 nm or less. The islands of metal may be less than 50 μm across. A conductivity of the anode active material layer and layer of metal may be less than 2×10Ω-cm.

H01M 4/66
H01M 4/02

Abstract:

Systems and methods for configuring anisotropic expansion of silicon-dominant anodes using particle size 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 utilizing a predetermined particle size distribution of silicon particles in the active material. The expansion of the anode may be greater for smaller particle size distributions, which may range from 1 to 10 μm. The expansion of the anode may be smaller for a rougher surface active material, which may be configured by utilizing larger particle size distributions that may range from 5 to 25 μm. The expansion may be configured to be more anisotropic using more rigid materials for the current collector, where a more rigid current collector may comprise nickel and a less rigid current collector may comprise copper.
