Sensors Expo 2018: The Industrial IoT Needs Industrial Batteries | Sensors Magazine
We live in an increasingly wireless world, with billions of consumer batteries being used to power laptops, cell phones, flashlights, cameras, toys, and other consumer goods. Meanwhile, the rapid growth of the Industrial Internet of Things (IIoT) has accelerated demand for lesser known applications that are powered by industrial grade batteries which feature extended operating life, can survive extreme environments, and deliver periodic high pulses to power two-way wireless communications.
Numerous primary (non-rechargeable) battery chemistries are commercially available including alkaline, iron disulfate (LiFeS2), lithium manganese dioxide (LiMNO2), lithium thionyl chloride (LiSOCl2), and lithium metal oxide (see Table 1).
Alkaline cells are extremely inexpensive, but have major drawbacks, including low voltage (1.5 V), a limited temperature range (-0°C to 60°C), a high annual self-discharge rate that reduces life expectancy to 2-3 years, and crimped seals that may leak.
