What is a nickel-zinc battery?

Nickel-Zinc battery is a rechargeable electrochemical cell, a device that converts stored chemical energy directly into electricity. The anode or negative battery terminal is made of zinc and cathode or a positive nickel terminal. The electron flow is from the anode to the cathode via the electrolyte medium that provides charged particles that carry electric current. Alkaline electrolytes that are not acidic alkaline are usually used in the nickel-zinc battery. Recharge reverse the electrochemical reaction and reconstructs the original chemical structure of the cell.

, which is sometimes mentioned by its elementary abbreviation, Nizn, Nickel-Zinc battery patented by Thomas Edison in 1901. The relatively high energy density, the amount of energy stored in a given volume and the easy availability of the battery raw materials supported the ongoing research, but.

In the early versions of the nickel-zinc batteryshowed as unstable over time. The zinc oxide produced by the anode created dendrites or fibers in the electrolyte. Dendrite formation caused the cell to be responsible for short -circuit and subsequently led to a limited number of charging/recharge cycles. NONSIBILITY also inhibited the complete restoration of the cell when it was charged, leading to the deformation of the anode terminal.

Alkaline electrolyte solutions have been developed that stabilize the zinc electrode, which, together with the internal polymer separator, overcomes the problems resulting from the formation of dendrite and deformation of the terminal. Progress in material science also made it possible to produce zinc and nickel terminals without elements of heavy metals. A more powerful and longer permanent battery than it was possible for earlier technology is the result. Charging the ability was increased both in the number of cycles and in the return of the cell to the original chemical state.

One of the advantages of the Nikl-Zinc battery is its abilityReplace primary or unloaded batteries in consumer electronics. These devices usually require 1.5 in the primary alkaline battery and would work well with the Nizn 1.65V rechargeable assessment. Other recharge patterns such as nickel-cadmia batteries usually have a nominal voltage of 1.2 V, which could lead to the failure of the device before the battery is completely discharged.

Nickel-Zinc battery is perceived as an ecological alternative to more common designs. Nickel and zinc are relatively abundant and everyone can be fully regenerated by recycling. Mercury, cadmium, lead or other toxic metals are not used or no flammable or corrosive active materials.
