Nickel-zinc batteries offer a reliable energy storage solution for applications that require maintenance-free electrical rechargeability, with good specific energy and cycle life, and low environment impact. The battery design features a nickel oxyhydroxide cathode with an aqueous alkaline electrolyte and a zinc anode.
Nickel–zinc has been invented in 1899 and produced commercially from 1920. The positive electrode also uses the same material, and for the anode electrode, a pasting of zinc oxide is used. Due to the high cell voltage, the energy density is about double of the nickel–cadmium and nickel–iron-based batteries. At the positive electrode,
In mildly acidic zinc-ion batteries, the goal is to support the transport of zinc species through the electrolyte to the cathode while avoiding all types of zinc salt precipitation. In this case Zn 2+ is the charge carrier between the half-cells.
The cells assembled with ZnNi alloy anode has excellent cycling performance. Aqueous zinc ion batteries are considered to be the new type of secondary batteries that have the potential to replace lithium-ion batteries as the most widely used in the future due to their green environment, high specific capacity and abundant zinc resources.
For example, zinc-air batteries are designed to sequester zinc as zinc oxide precipitated in the anode. In this case, the controlled precipitation of ZnO is desirable. On the other hand, zinc-ion batteries are designed to transport zinc ions across the cell to be intercalated into the cathode material.
In the Ni–Zn battery, the positive electrode is made of nickel oxide and the negative electrode is zinc metal. This type of battery exhibits a higher energy density (by about 25%) than Ni–Cd batteries. Ni–Zn batteries have a higher energy-to-mass ratio and power-to-mass ratio than conventional lead batteries.

Zinc Alloys are combinations of zinc with one or more other metals. If zinc is the primary constituent of the alloy, it is a zinc-base alloy. Zinc also is commonly used in varying degrees as an alloying component with other base metals, such as copper, aluminum, and magnesium. A familiar example of the latter is the association of varying amounts of zinc (up to 45%) with …
