Types of rechargeable batteries
Posted: Sun Dec 15, 2024 5:45 am
Lithium batteries: You have to differentiate between lithium batteries and lithium ion batteries . The first ones are disposable and have a capacity very similar to alkaline batteries, producing voltages between 1.5 V and 3.7 V. The second ones are rechargeable and are widely used in portable electronic devices. The negative point is that lithium batteries are much more polluting than alkaline batteries. Button batteries
are easily recognizable by their rounded and flat shape. They have a long life and are used in watches and hearing aids, for example. They are an example of a lithium battery. Rechargeable batteries: These have two or more canadian cto cio email list energy cells, in contrast to single-use batteries, which have one energy cell. For this reason, they are the most recommended, they can work for many years with the help of a battery charger.
Rechargeable batteries use different combinations of chemicals, the most commonly used being nickel-cadmium, nickel-metal hydride and lithium-ion.
Nickel-cadmium (NiCd) batteries
They are becoming increasingly obsolete. These batteries have a “memory effect” that reduces their capacity if they are not charged correctly. In addition, cadmium is a highly polluting element.
Nickel-metalhydride (NiMH) batteries
They have a higher energy density and do not have “memory” problems like NiCd batteries, although their self-discharge rate is high. They are not recommended for objects with long periods between uses, such as the television remote control. Because they have a higher internal resistance, the charging speed is slower than that of nickel-cadmium batteries.
Lithium batteries (Li-ion)
They are part of our daily routine, so much so that they are present in all mobile phones . They can be found in the form of traditional batteries with a higher energy density than the two previous examples, although their durability is lower.
Each of these types of batteries will need specific chargers, since they have different voltages.
Uses and applications of rechargeable batteries
We think of batteries as small objects, but in reality they have many uses and applications, some of which you might not even imagine.
Rechargeable batteries are used to power a television remote control or to recharge an electric car . Electric cars run on batteries, which are recharged in power supplies that run on rechargeable batteries, which supply electricity from charging points .
They are also used in light vehicles , such as monitored wheelchairs, electric bicycles, electric forklifts, etc. They are also used in household devices such as battery-operated thermostats and digital clocks.

Nowadays, there are many electronic devices that require batteries, and they are increasingly required to last longer. A rechargeable battery will always be preferable to a conventional one. Firstly, because it reduces the materials and energy used in its manufacture, which will pollute the environment much less and, above all, it prevents it from becoming a polluting waste that is difficult to dispose of.
In addition, an alkaline battery requires 50 times more energy in its manufacture than it actually provides to its recipient, while a rechargeable battery offers about 2,500 times more energy .
