A zinc metal negative electrode holds a high theoretical volumetric capacity (5854 Ah L-1), gravimetric capacity (820 Ah kg-1), and natural abundance. [2] Zinc production and proven reserves exist at a higher scale than lithium metal due to zinc’s use in galvanization and its broad geographic availability. [12]
Zinc iodide is often used as an x-ray opaque penetrant in industrial radiography to improve the contrast between the damage and intact composite. [8] [9]United States patent 4,109,065 [10] describes a rechargeable aqueous zinc-halogen cell that includes an aqueous electrolytic solution containing a zinc salt selected from the class consisting of zinc bromide, zinc iodide, and mixtures thereof ...
The zinc-chloride cell, frequently referred to as a heavy-duty, extra-heavy-duty, super-heavy-duty, or super-extra-heavy-duty battery, is an improvement on the original zinc–carbon cell, using purer chemicals and giving a longer service life and steadier voltage output as it is used and offering about twice the service life of general-purpose ...
2.4 V Can operate up to 150 °C. Developed as a replacement of zinc–carbon and alkaline batteries. "Voltage up" problem, the high difference between open-circuit and nominal voltage. Produced until the mid-1990s, replaced by lithium–iron sulfide. Current use is limited. Li–Cu 4 O(PO 4) 2: Copper oxyphosphate: See Li–CuO Li–CuS Copper ...
Zinc–air hearing aid batteries PR70 from both sides. Left side: Anode and gasket. Right side: Cathode and inlet opening for the atmospheric oxygen. A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air.

Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
2 Zn(OH) 2 + 4 e − ⇌ 2 Zn + 4 OH −. The process is continued until the cell potential reaches a level where the decomposition of the electrolyte is possible at about 1.55 volts. This is taken as the end of a charge, as no further charge is stored, and any oxygen that might be generated poses a mechanical and fire hazard to the cell.
