Nickel Zinc batteries
Nickel Zinc batteries
Nickel Zinc batteries are replaced with Zinc in which the negative electrode material (hydrogen storage alloy) of a nickel-metal hydride batteries are replaced with a zinc compound. . Since it can be charged using a similar charging method to lead-acid batteries, it is relatively easy to replace lead-acid batteries.
Features of FDK's Nickel Zinc batteries
FDK's Nickel Zinc batteries applies the positive electrode and manufacturing technologies used in Ni-MH hydride batteries for long time and the zinc negative electrode technology used in alkaline dry cell for long time. The features of FDK's Nickel Zinc batteries are as follows.
- Compared to the lead-acid batteries, it has approximately twice the weight energy density
- Compared to the lead-acid batteries, it has the charge/discharge cycle is approximately three times longer
- Since it uses zinc that is a rich resource in the world, it does not use harmful substances such as lead.
- Since this product can be charged using a similar charging method (CC+CV) of lead-acid batteries, making it relatively easy to replace lead-acid batteries.
- Because it has a water-based electrolyte, there is less risk of fire, etc., and it has highly safe.

FDK's original technology
Nickel Zinc batteries have had problems with shorter cycle durability due to dendrite short circuits and battery capacity deterioration, but the FDK's Nickel Zinc batteries currently under development has addressed these issues by reviewing the battery components. We have further improved the positive electrode material※1, which is FDK's original technology, and have confirmed that it has achieved a making useful level of cycle durability as shown in the figure below. ※2
