What Is a Primary Cell or Battery? 

Batteries are energy storage devices used in everything from medical devices to handheld electronics. They work by converting energy generated by chemical reactions into usable electrical energy. Each battery typically consists of two components—a positive anode and a negative cathode—also known as electrodes.

These electrodes are where the chemical reactions occur within the battery. There is an electrical difference between the anode and cathode. However, since there is no direct connection between them, the electrons stay in place until the battery is inserted into a device. At this point, the electrical circuit is completed, allowing energy (i.e., the electrons) to flow from the battery to the device. 

A primary cell or battery is one that cannot easily be recharged after one use, and are discarded following discharge. Most primary cells utilize electrolytes that are contained within absorbent material or a separator (i.e. no free or liquid electrolyte), and are thus termed dry cells.

What are the various types of Primary Batteries?

There are various types of primary cells or batteries to include alkaline and lithium thionyl chloride.

  • Alkaline batteries offer improved performance and life than non-alkaline batteries such as zinc carbon.  They are cost competitive, demonstrate a long shelf life, readily available at retail, and commonly used in consumer electronics to include wireless peripherals, gaming consoles, toys, and household medical devices.
  • Lithium thionyl chloride offer many benefits compared to other lithium primary chemistries to include lithium manganese dioxide.  Lithium thionyl chloride offers a high voltage, greater energy density with lower weight, and a wider temperature range for extreme cold and hot applications.  Lithium thionyl chloride batteries are commonly used in outside applications subject to wide temperature ranges.  For instance, devices include sensors that power transportation toll collection, utility meters, or emerging IoT devices.
