These have replaced mercury–zinc batteries, which were banned in the United States in 1996 as they contained 30–40% of toxic mercury. Silver–zinc batteries are manufactured in the form of button and rectangular cells with free potassium hydroxide electrolyte, or alkaline electrolyte immobilized by adding thickening agents (Figure 2).
At that time, silver–zinc batteries became the preferred system for many other applications. Some of the unique systems include the largest silver–zinc battery ever made, a 256-ton battery for the Albacore G-5 submarine. This battery consisted of a two-section, two-hundred-and-eighty-cell battery, with each cell rated at 20,000 A h.
