Why Zinc Nickel Alloy Plating Is Replacing …
In 1956, over 60 percent of all cadmium was used for coating iron or steel. However, over the years, this has decreased to as little as 7 percent in 2006, and materials like zinc nickel plating are seeing more and more use. In Search of Alternatives When the industry was looking for a viable replacement to cadmium, they tried zinc electroplate.

Uwe Koehler, in Electrochemical Power Sources: Fundamentals, Systems, and Applications, 2019. 2.3.2.3 Nickel–metal hydride (NiMH) batteries. Nickel–metal hydride batteries [1,3,9,23] in most aspects of their design and concerning their manufacturing processes are similar to NiCd batteries. The main difference is in the replacement of the negative cadmium-based electrode with an electrode ...
Nickel–cadmium battery - Wikipedia
Positive and negative plates are produced by soaking the nickel plates in nickel- and cadmium-active materials, respectively. Sintered plates are usually much thinner than the pocket type, resulting in greater surface area per volume and higher currents. In general, the greater amount of reactive material surface area in a battery, the lower its internal resistance. Since the 2000s, all ...
