Cadmium is also the manufacture of foam - nickel batteries and hydrogen - nickel batteries, one of the best electrode materials. Electricity through the test successfully developed technology to prepare nickel foam deposition process. Substrate materials used in the hole for the porous foam, the use of chemical nickel plating, vacuum plating nickel and immersion conductive adhesive can be prepared by three methods conductive layer, after the pre-plated nickel sulfate can be in a common electrolyte in the electroplating thick nickel-plated nickel, the latter through the burning, reduction, annealing process can get excellent performance of the foam material.
