BU-407: Charging Nickel-cadmium

Battery manufacturers recommend that new batteries be slow-charged for 16–24 hours before use. A slow charge brings all cells in a battery pack to an equal charge level. This is important because each cell within the nickel-cadmium battery may have self-discharged at its own rate. Furthermore, during long storage the electrolyte tends to

SPH Ni-Cd battery Technical manual

During discharge the trivalent nickel hydroxide is reduced to divalent nickel hydroxide and the cadmium at the negative plate forms cadmium hydroxide. On charge, the reverse reaction takes place until the cell potential rises to a level where hydrogen is evolved at the negative plate and oxygen at the positive plate which results in water loss.

6 FAQs about [Charge and discharge of nickel-cadmium batteries]

How stable is a nickel cadmium battery?

Nickel–cadmium batteries, unlike some other battery systems, show very stable voltage of 1.2 V for the majority of the discharge process up to the point where there is a “knee” in the curve and a sharp drop at the end of discharge (Fig. 4.6). The point when the battery reaches 0.9 V is considered the end of discharge and full capacity.

What causes a nickel cadmium battery to fail?

The most common failure modes in nickel–cadmium batteries are electrical shorts caused by the growth of cadmium dendrites and penetration through the separator, passivation, and wear of active materials, destruction of the separator, and swelling of positive active mass.

What are the disadvantages of nickel cadmium battery?

Other disadvantages of nickel–cadmium battery are the high rate of self-discharge, poor performance at high temperatures, and complex charging. During discharge reaction in N–Cd battery, cadmium is oxidized on the negative electrode to form Cd (OH) 2 and electrons (Fig. 4.1).

Why is overcharge a ni cadmium battery a problem?

The overcharge is an undesirable process in Ni–Cd batteries because it leads to generation of gasses and increase in both pressure and temperature that can catastrophically damage a battery. Since most nickel–cadmium batteries are sealed, a special design approach was needed to control the overcharge and to prevent any damage to battery.

How do you keep a nickel cadmium battery fully charged?

A useful procedure to maintain full capacity of nickel–cadmium batteries at all times is to use trickle charge simply to offset the self-discharge rate and keep the battery fully charged. If this is not possible, a battery should be stored in cool conditions.

Does nickel cadmium battery have potassium hydroxide?

In the charge/discharge reaction of the nickel-cadmium battery, the potassium hydroxide is not mentioned in the reaction formula. A small amount of water is produced during the charging procedure (and consumed during the discharge).
