A rechargeable battery is provided such that the positive electrode comprises lead dioxide, the negative electrode zinc, and the electrolyte is alkaline. Upon discharge, the lead dioxide is reduced to lead oxide, the zinc is oxidized to zinc oxide, and the electrolyte remains unchanged. The reactions are reversed when the battery is charged.


Aug 08, 2021· The first step is to add the zinc plating, through the use of electrical current. The second step is to treat the plated metal with a chemical passivate which adds color. These solutions are referred to as chromates (hex chrome) or passivates (tri chrome). To create a clear finish, a clear passivate is used.

Zinc - Consumer

Zinc is a nutrient that people need to stay healthy. Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. The body also needs zinc to make proteins and DNA, the genetic material in all cells. During pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly.
