CAPACITOR-ASSISTED CURRENT COLLECTOR

A battery for a vehicle battery pack, a capacitor-assisted current collector, and a method is provided. The vehicle battery pack includes a battery pack housing and at least one vehicle battery cell carried by the battery pack housing. The at least one vehicle battery cell includes a cathode, an anode, a separator, and an electrolyte. The at least one vehicle battery cell further includes a current collector and a multi-functional coating layer disposed on and adhered to at least one side of the current collector. The multi-functional coating layer is configured to provide fast charge capability for the vehicle battery pack. 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.
