Self-powered electronic devices that define the Industrial Internet of Things (IIoT) have special needs that can be addressed through the judicious selection of battery chemistry. SOL JACOBS | TADIRAN BATTERIES Going ‘truly wireless’ typically necessitates the use of primary (non-rechargeable) or rechargeable lithium-ion (Li-ion) batteries. Besides untethering applications from ac lines, use of rechargeable batteries […]
EV technology goes industrial: Scenes from the Battery Show
Attendees of this year’s Battery Show in Novi, Mich., could be excused for not knowing what to expect on the show floor as trade events start to come back from a year-and-a-half hiatus. The above clip gives a glimpse of what the experience was like. Aside from the occasional mask wearer, it seemed like business […]
Solid-state EV batteries – are we there yet?
The short answer is ‘no.’ We might be getting closer, but there’s still no guarantee that we’ll get there soon. Some automakers are looking at 2024 for the introduction of solid-state batteries in EVs, but others don’t see that happening until 2030. Expectations are high but unfulfilled. This FAQ reviews the anticipated benefits of solid-state…

Alif Semiconductor announced the launch of its Ensemble™ and Crescendo™ product families. Built to power the exponential expansion of next-generation, always-connected IoT products, the Ensemble and Crescendo families fill the market need for scalable, genuinely power-efficient devices that integrate AI/ML acceleration, multi-layered security, LTE Cat-M1, and NB-IoT connectivity, GNSS positioning, and plenty of integrated memory […]
EV battery thermal management challenges
Keeping EV batteries cooled is the most common thermal management concern. However, batteries used in cold climates often benefit from being heated when temperatures fall. When undergoing fast charging or extra fast charging (XFC) batteries may need additional levels of cooling. This FAQ first considers various active and passive cooling technologies for EV batteries. It…
What are TENGs and PENGs and what are they good for?
Small self-powered systems, including wireless sensors and small robots currently under development, can use triboelectric nanogenerators (TENGs) and piezoelectric nanogenerators (PENGs) as prime power sources. TENGs and PENGs offer large open circuit voltages, low materials cost, ease of fabrication, and good energy conversion efficiencies. TENGs use triboelectricity, commonly called static electricity, to convert common mechanical […]
Group14 Technologies and InoBat partner to deliver lithium-silicon batteries to automakers
Group14 Technologies, a global provider of silicon-carbon composite materials for lithium-ion markets, and Inobat Auto, a European battery R&D and manufacturing company, announce a partnership to custom manufacture high energy density batteries for automotive applications. As major global automakers continue to make commitments to all-electric lineups, the demand for higher-performing energy storage is continuing to…
Sweat and tears make stretchable batteries better
A group of researchers hailing from Nanyang Technological University in Singapore have devised stretchable silver electrodes whose conductivity can be enhanced by human sweat. The stretchable electrodes were fabricated by directly printing an ink composed of conductive silver flakes and specially designed elastic binder called hydrophilic poly(urethane-acrylate) (HPUA) on hydrophilic textiles. Researchers say the HPUA…
Battery pack protection keeps EVs on the road
A few best practices for handling transients and over-currents help make electronic drivetrains more reliable. James Colby • Littelfuse, Inc. Automotive market analysts predict that by 2025, high-end vehicles will contain more than $6,000 in electronic components. Most of these advanced electronics will be in the growing number of electric vehicles (EVs). To ensure robust, […]
