Method and system for pulverization mitigation additives for silicon dominant anodes

A method of forming an electrode, the method comprising:

• providing a metal current collector;
• and
• providing an active material layer on the current collector, wherein the active material layer comprises:
• islands of material separated by cracks, the islands comprising:
• silicon;
• pyrolyzed binder;
• and
• conductive additives, wherein at least a portion of the additives extend from within the islands and bridge the cracks of the active material layer;
• wherein:
• the conductive additives comprise one-dimensional (1D) conductive additives, two-dimensional (2D) conductive additives, and three-dimensional (3D) conductive additives;
• and
• one of the 1D conductive additives, the 2D conductive additives, and the 3D conductive additives is at least 4× of the conductive additives of other dimensions.

A battery, the battery comprising:

• a battery comprising a cathode, an electrolyte, and an anode comprising a metal current collector and an active material layer on the current collector, wherein the active material layer comprises:
• islands of material separated by cracks, the islands comprising:
• silicon;
• pyrolyzed binder;
• and
• conductive additives, wherein at least a portion of the additives extend from within the islands and bridge the cracks of the active material layer;
• wherein:
• the conductive additives comprise one-dimensional (1D) conductive additives, two-dimensional (2D) conductive additives, and three-dimensional (3D) conductive additives;
• and
• one of the 1D conductive additives, the 2D conductive additives, and the 3D conductive additives is at least 4× of the conductive additives of other dimensions.
