Nickel-cadmium batteries

Nickel-cadmium batteries are considered one of the most common batteries for energy storage. The composition contains 2 electrodes. As you can guess from the name, nickel and cadmium. Nickel hydroxide is mixed with a conductive substance, and cadmium is pressed into a steel mesh. The electrodes are separated from each other by a space filled with alkali. A reversible chemical process occurs in which cadmium, nickel and water are involved.

Reliable and productive: the advantages of nickel-cadmium batteries

Units with nickel and cadmium electrodes have come into use since the first half of the 20th century. Since then, these devices have been used for both domestic and professional use. It is easy to buy nickel-cadmium batteries in Kyiv and other cities, because this model is extremely common. And it’s not surprising, because it has several advantages.

1. Storage in a discharged state. Unlike lead-acid alternatives, nickel-cadmium batteries do not lose their properties if stored in a discharged state.
2. Low resistance. This characteristic indicates that the battery does not heat up when charging. It just needs to be disconnected from the network in time to extend its service life.
3. Use at low temperatures. The battery is resistant to temperature fluctuations and does not lose performance. For example, the EverExceed brand product line remains operational within temperatures from -50 to +70°C.
4. Long service life. Some batteries can withstand over 900 charge-discharge cycles, and some are capable of 2000 cycles. If operating and storage conditions are observed, the battery will last up to 25 years.
5. Compact and lightweight. For example, EverExceed XHP60 weighs 3.8 kg with dimensions of 62x138x267 mm, so it does not take up much space and is suitable for frequent transportation.

If you want to buy nickel-cadmium batteries in Kyiv and other cities, take into account some of the features of its operation. So, this battery is capable of rapid self-discharge, so leaving the device charged for a long time is impractical. As for prices, these models belong to budget options. They can be purchased at a low price due to their simplicity of design and operation.

Nickel-cadmium batteries: the optimal solution for high loads

To power cars, river, sea, air and public transport, as well as other consumers, it is worth buying nickel-cadmium batteries. This is the optimal solution for high loads when the consumer requires a lot of energy.

For efficient operation, discharge the unit completely. The fact is that this model has a pronounced “memory effect”. That is, the battery “remembers” to what point it was charged, and upon subsequent use it will release the same amount of energy.

Over time, nickel-cadmium batteries decrease in capacity. This is a normal process for this type of battery. But the capacity can be partially restored. To do this, carry out several complete charge-discharge cycles to minimize the “memory effect”.

If you decide to buy a device, pay attention to:

• capacity;
• weight;
• dimensions;
• voltage.

The number of charge-discharge cycles is of no small importance when choosing a unit.

History and principle of operation of nickel-cadmium batteries

Nickel-cadmium batteries are batteries in which chemical reactions are converted into energy. For the first time such an energy storage device appeared in use back in 1899. The positive electrode in the first development was made of nickel, and the negative electrode was cadmium. Later, iron came to replace cadmium.

However, the initial development never came into use due to the high cost of components - it was simply unprofitable to buy such a battery. The popularity of Ni- Cd aggregates flared up only in the early 30s of the last century, when a compressed anode was introduced into use - more durable and resistant to stress. The final improvement of Ni- Cd storage devices occurred in the late 40s after many experiments resulted in the invention of a sealed cell.

It is extremely easy to buy nickel-cadmium batteries, because... This is one of the most common types of batteries. Positive and negative electrodes in the structure are arranged alternately. They are separated by a separator. Nickel hydroxide with graphite powder is the anode, cadmium hydroxide is the cathode. Potassium and lithium hydroxides are used as electrolytes. The housing is sealed plastic or made of nickel-plated sheet metal.

Many people want to buy nickel-cadmium batteries in Kiev because the service life of a modern Ni- Cd drive is long. Some models for industrial use can last more than 25 years.

Comparison with other battery types: where do nickel-cadmium win?

The market offers energy storage devices with different chemical compositions: lithium-ion, lead-acid, gel , nickel-cadmium. The latter variety is in demand due to its relatively low cost, maximum load current output and fast charging .

Nowadays it is not difficult to buy nickel-cadmium batteries in Kyiv and other cities. This model is in demand because it can withstand about a thousand charge-discharge cycles. In comparison, lithium-ion batteries are designed for approximately 300 cycles. If you value durability, then the Ni- Cd model is the best choice.

An indisputable advantage, because of which many people want to buy nickel-cadmium batteries, is the price. The cost of such units is much lower than, for example, gel units . The production technology is simpler; therefore, they can be purchased inexpensively. If you need to buy a reliable energy storage device inexpensively, this model is the best choice.

Another advantage of the device is the delivery of maximum load current. At the same time, this type of battery, compared to lithium-ion batteries, has one feature - the “memory effect”. They record the charge level that remains before recharging, which subsequently negatively affects the energy intensity. In untreated cases, the energy capacity can be restored by a cycle of complete discharge and charging.

Such models like fast, rather than measured charging. However, be careful not to overcharge. Ni- Cd drives react extremely negatively to it. Please note that this type of device self-discharges quickly. If you have not used the unit for a long time, it will have to be recharged.

Nickel-cadmium batteries, unlike lithium ones, can be stored completely discharged. This will not affect the energy consumption of the unit in the future. As for environmental friendliness, Ni- Cd batteries are somewhat inferior to other models. But if handled with care, avoiding overheating and maintaining the integrity of the case, such a device will not cause any harm.
