Mobility and portability are advantageous features that electronic devices can have, allowing them to be transported and used in countless environments with ease. For an electronic device to function without a constant supply of power being provided through cabling, it will need a form of battery or battery pack. From car engines to telecommunication equipment, batteries of all types can be found, providing for countless applications and operations that we rely on. In this blog, we will provide a brief overview of some of the most common batteries that are found in wireless electronic devices, allowing you to better identify each for the management of systems.
No matter the design of a particular battery, all can be defined as being a collection of one or more cells that store energy that is used by electrical devices. Through various chemical reactions during operations, a flow of electrons will enter the circuit, allowing for stored chemical energy to be transformed into usable direct current power. The cells themselves are a major element of the battery, and they always contain two electrodes (the anode and cathode) and an electrolyte. For energy conversion to take place within a battery, the anode will lose electrons to the external circuit while the cathode accepts electrons. Meanwhile, the electrolyte is the medium for electrodes to transfer ions. Throughout typical operations, the cells will ensure that needed voltage and current levels are upheld.
Batteries are typically classified as either non-rechargeable or rechargeable, those of which are known as primary and secondary types respectively. Primary batteries are convenient and cheap, and they are used for portable devices such as radios, cameras, lights, watches, and more. As they are unable to be charged, they will need to be disposed of in a safe manner once they run out of power. Despite the one-time use feature, primary batteries are often the top choice for their lack of maintenance, lightweight design, ease of use, and low price point. Alkaline batteries are the most popular option, featuring high performance with a potassium hydroxide electrolyte. Nevertheless, there are many other options such as magnesium, mercury, lithium, silver/zinc, and zinc-carbon types.
Secondary batteries widely differ from primary batteries in their ability to be recharged for continued use. This feature often makes them more expensive, but this is offset by their long lifespan and ability for reuse. Secondary batteries are often used as an energy storing bank, allowing them to supply and store energy for uninterrupted power supplies, hybrid electric vehicles, and much more. When placed in such assemblies, the secondary battery acts as an energy storage bank for the main energy source. In other instances, the secondary battery is used for applications where it is discharged as the primary battery, and examples include mobile phones, laptops, and electric vehicle batteries. While they are used as a primary battery, they can still be recharged when all energy is spent. There are numerous forms of secondary batteries, the most common including lead-acid, nickel cadmium, nickel metal hydride, and others.
When choosing a battery for a particular application, one should consider classifications, energy requirements, shelf life, energy efficiency, battery life, and battery temperature.
