Abstract
A cathode current collector is made from a composite material including a first metallic layer made of a first metal and a second metallic layer made of a second metal different from the first metal. The first metallic layer is cladded with the second metallic layer. The first metallic layer is configured to form a conductive oxide corrosion layer in the presence of oxygen, molten carbonate electrolyte, or a combination thereof. The second metallic layer is corrosion resistant.
