Abstract
A hot-dip coating system comprising a substrate pathway comprising one or more rollers configured to move a substrate along the substrate pathway between a first end and a second end, a pre-coating section arranged with respect to the substrate pathway and configured to apply a first coating to the substrate, a pre-heating section arranged with respect to the substrate pathway and configured to heat the substrate and the first coating, and a hot-dip coating section arranged with respect to the substrate pathway and configured to apply a second coating to the substrate.

A hot-dip coating system, comprising:
- a substrate pathway comprising one or more rollers configured to move a substrate along the substrate pathway between a first end and a second end;
- a pre-coating section arranged with respect to the substrate pathway and configured to apply a first coating to the substrate;
- a pre-heating section arranged with respect to the substrate pathway and configured to heat the substrate and the first coating;
- and
- a hot-dip coating section arranged with respect to the substrate pathway and configured to apply a second coating to the substrate.
A method of manufacturing a current collector for a battery of a vehicle comprising:
- providing a substrate including a first surface, a second surface opposite the first surface, a first side, and a second side spaced laterally from the first side;
- applying a mask to a portion of the first surface and the second surface and the first and second sides of the substrate;
- applying a first coating to the first surface and the second surface of the substrate;
- pre-heating the substrate and the first coating with one or more heaters arranged adjacent to the substrate;
- submerging the substrate in a molten bath of a second coating so that the second coating can adhere to the substrate;
- removing the mask;
- and
- trimming the substrate at the first side and the second side.
