  • Publication number: 20250006899
    Abstract: An anode electrode for use in a lithium-ion battery cell including silicon and a porous carbonaceous anode electrode coating is provided. The anode electrode includes an electrode substrate including a current collector and the porous carbonaceous anode electrode coating. The electrode coating includes a surface material including graphite, wherein the surface material includes a plurality of sphere-shaped depressions, carbon particles, and a plurality of silicon particles affixed to inner walls of the plurality of sphere-shaped depressions. The sphere-shaped depressions are configured for receiving expansion of the plurality of silicon particles when the silicon particles are in a lithiated state.

  • Publication number: 20240194893
    Abstract: An electrode for a rechargeable battery cell includes an electrode substrate. The electrode also includes a current collector fixed to the electrode substrate and having a three-dimensional (3D) porous structure defining void spaces. The electrode additionally includes active material particles arranged within the void spaces. Charging the battery cell reversibly deposits transient ions onto the active material particles and expands the active material particles into the void spaces of the 3D porous structure and discharging the battery cell extracts the transient ions from the active material particles, such that the active material contracts out of the void spaces of the 3D porous structure. A method of manufacturing such an electrode for a rechargeable battery cell is also considered.
