Capacitor-assisted current collector

A capacitor-assisted current collector, comprising:

• a current collector;
• and
• a multi-functional coating layer adhered to at least one side of the current collector, wherein the multi-functional coating layer is configured to provide fast charge capability for a vehicle battery pack, and wherein the multi-functional coating layer includes
• a capacitor material configured to enhance pulsed and continuous charge rate capability;
• a conductive filler configured to provide electrical conductivity;
• and
• a binder configured to provide adhering capability between the multi-functional coating layer and the current collector.

A method for forming a capacitor-assisted current collector, comprising:

• mixing a first slurry using a solvent, wherein the first slurry includes a conductive carbon;
• intaglio printing the first slurry on an aluminum current collector;
• and
• drying the first slurry using a heater to form a dried first slurry layer and multi-functional coating layer, wherein a solid content of the multi-functional coating layer is about 20 weight %, and wherein the multi-functional coating layer is configured to provide fast charge capability for a vehicle battery pack.
