The modern world is filled with electronics: from the smallest devices in the form of a flashlight to huge equipment in production. But not all of them work from a direct source of energy, many of them function thanks to mobile devices, for example, such as alkaline batteries.
Among them, there are two main types: iron-nickel and cadmium-nickel. The mass for the positive plates of both types of batteries is nickel oxide hydrate, for the negative ones it is a mixture of cadmium and iron. Charging alkaline batteries begins with a current of 1.5 volts, after which the voltage is gradually increased to 1.8 volts. It should be noted that as the temperature drops, the battery capacity decreases by 0.5% per degree.
Let's highlight the advantages that alkaline batteries have over lead-acid batteries:
1. Rare and scarce lead is not used in their manufacture.
2. Increased mechanical strength and endurance (not afraid of shocks, shaking and short circuits).
3. alkalineBatteries last much longer even when idle for long periods.
4. Batteries emit less fumes and harmful gases.
5. Compared to lead, they are quite light.
6. Less demanding to care.
Alkaline batteries also have disadvantages:
1. EMF is less than that of lead acid.
2. Efficiency is approximately 40 - 50% lower.
3. The cost is much higher.
Today, alkaline batteries are used only in machines that operate under severe operating conditions, or where durability and reliability are needed (construction and agricultural machinery). Let's talk about the two main types of batteries, namely nickel-cadmium and nickel-metal hydride.
The first nickel-cadmium batteries began to be produced in 1950. Since then, they have been fully explored. The improvement of innovative production technologies has made it possible to significantly increase their characteristics. The capabilities of these batteries are actively used today in various equipment (even in space) and special equipment. It is important to note that domestic products of this type differ from foreign counterparts, because abroad they are produced in separate batches for specific consumer requests.
Nickel-metal-hydride alkaline batteries are less popular due to the fact that over the past decade they have been greatly supplanted by nickel-cadmium designs. Recent research has significantly improvedcharacteristics. Due to environmental concerns, the study of cadmium batteries is gradually declining, and metal hydride batteries are preferred, but, unfortunately, their popularity has not yet gained momentum.
In the end, I would like to note that the efficiency, and most importantly, the duration of operation, mainly depends on the chargers, which must provide a clear control of the charging process under various conditions. Therefore, when purchasing alkaline batteries, carefully study their characteristics and their operating conditions.
