Metallized current collector devices and materials

A multi-cell battery comprising:

• a first cell including a first current collector, a first anode, a first cathode, and a second current collector;
• a second cell including a third current collector, a second anode, a second cathode, and a fourth current collector, wherein the second current collector and the third current collector are coupled with one another across a portion of a first surface of each of the second current collector and the third current collector;
• a first seal between the first current collector and the second current collector;
• a second seal between the third current collector and the fourth current collector;
• and
• a metal liner coupled with the first surface of each of the second current collector and the third current collector.

A battery cell comprising:

• a first current collector;
• a second current collector;
• a cathode active material coupled with a first area of a first surface of the first current collector;
• an anode active material coupled with a first area of a first surface of the second current collector;
• a seal between a second area of the first surface of the first current collector and coupled with a second area of the first surface of the second current collector;
• and
• a metal material coupled with the first surface of at least one of the first current collector and the second current collector between the first area of the first surface and the second area of the first surface of a respective current collector for the first area and the second area.
