Rechargeable lithium-ion batteries get a lot of headlines, but primary Li battery chemistries are the workhorses in a large number of industrial, medical, consumer, and other applications. This article looks at the performance tradeoffs and typical applications for the six most common Li primary chemistries including LiCFX (lithium poly carbon monofluoride) LiMN02 (lithium manganese dioxide),…

Energy harvesting (EH) can be an attractive way to power wireless internet of things (IoT) and other small devices. EH can be combined with rechargeable batteries, capacitors, or supercapacitors to provide enhanced performance. Depending on the circumstances, primary batteries can provide a more reliable and even lower-cost option. This FAQ looks at ways to classify…

Self-discharge refers to the declining state of charge of a battery while the battery is not being used. In most instances, self-discharge cannot be eliminated but needs to be managed. Too high a self-discharge rate can limit the potential applications for a battery. Depending on the battery chemistry and construction, there can be several causes…

By Pamela Mansfield, JEOL USA  As the market for renewable energy sources and electric vehicles grows, the need for reliable, high-capacity energy storage is increasing too. Lithium-ion batteries (LIBs) fit the bill in many ways, but plenty of challenges remain ahead, such as understanding their microstructure. This article describes how scanning electron microscopy (SEM) can…

That depends. There is a wide range of regulations for lithium (Li) batteries. Some regulations, like those related to the transport of Li batteries and Li battery packs, have a broader impact than application-focused regulations like those for Li battery packs in electric vehicles (EVs) or industrial systems. This FAQ begins by looking at three…

That’s a complex and dynamic question without a simple answer. The electrification of everything is expected to lead to post-lithium-ion battery (LIB) technologies like potassium-ion batteries (PIBs), sodium-ion batteries (SIBs), and possibly more exotic chemistries. In the near term, the dominance of LIBs will be almost unassailable. The key word is “almost”. Among the keys…

Electrochemical impedance spectroscopy (EIS) can be used for estimating the power delivery capability and state of health (SoH) of Li-ion batteries. It is important because it has the potential to improve rapid and accurate SoH monitoring of Li-ion batteries and support more sustainable battery storage systems for electric vehicles (EVs) and grid-scale energy storage systems.…

While lithium-ion battery chemistry dominates the current electric vehicle market, scientists are working to develop innovative battery chemistries that address the known challenges the existing chemistry presents. By Adam Kimmel for Mouser Electronics Sales of electric vehicles (EVs) continue to outpace the overall automotive segment, with EV market shares of 5.2% in Q1 and 5.6%…

By Sol Jacobs, Tadiran Batteries At the heart of the IIoT are lithium battery-operated remote wireless devices that bring digital connectivity to emerging and evolving technologies such as SCADA, process control, industrial robotics, asset tracking, safety systems, environmental monitoring, M2M, AI, and wireless mesh networks, to name a few. Battery-powered remote wireless devices serve to…

Thermal runaway happens when a lithium-ion cell, or a small region within a cell, reaches a critical temperature where the materials start to undergo decomposition reactions. These reactions then generate significant additional heat. The decomposition reactions are temperature dependent, increasing exponentially as the temperature increases. Once decomposition starts, a chain reaction causes the battery to…
