What’s The Buzz At The Battery Show?


Hwee Yng Yeo catches up with Christian Loew, Keysight’s solution manager for battery pack and module test, to find out what was abuzz on the floor of The Battery Show in Stuttgart recently. Hwee Yng: Christian, could you tell us what was the main buzz at The Battery Show this year? Christian: There were two topics topping the buzz list at the show – on the R&D side, new sodium i... » read more

High Performance, Energy-Dense, Practical, And Reliable Solid-State Batteries (ORNL)


A technical paper titled “Tailoring of the Anti-Perovskite Solid Electrolytes at the Grain-Scale” was published by researchers at Oak Ridge National Laboratory. Abstract: "The development of thin, dense, defect-free solid electrolyte films is key for achieving practical and commercially viable solid-state batteries. Herein, we showcase a facile processing pathway for antiperovskite (Li2OH... » read more

Five Smart Ways To Improve EV Battery Production


Batteries and battery management systems are the heart of today's electric vehicles. These components define the performance, safety, and driving range of more than 16.5 million1 electric vehicles currently on the road. As electric vehicle and battery manufacturers continue to look for ways to increase the efficiency and speed of their production processes, many turn to Nordson EFD for prec... » read more

Week In Review: Semiconductor Manufacturing, Test


Imec released its semiconductor roadmap, which calls for doubling compute power every six months to handle the data explosion and new data-intensive problems. Imec named five walls (scaling, memory, power, sustainability, cost) that need to be dismantled. The roadmap (below) stretches from 7nm to 0.2nm (2 angstroms) by 2036, and includes four generations of gate-all-around FETs followed by thre... » read more

Brrraaap: Full Throttle On Dirt Bike Electrification


On a dirt bike almost any terrain is fair game. Once you hit the back roads, course correcting through open fields or wooded areas to get where you’re going (or not) is easy. These powerful-yet-agile gravel-and-dirt surfing, rock-hopping machines have been identified by some as the undisputed off-road champions — perfect for exploration in places larger vehicles simply can’t go. Dirt b... » read more

The Good And Bad Of Bi-Directional Charging


Auto OEMs are starting to offer bi-directional charging in EVs, allowing batteries to power homes during outages or wherever else it is needed, and to smooth out any hiccups in the grid. But this technology also can shorten the lifetime of batteries, and it can open the door to more cyberattacks. The idea behind bi-directional charging is simple enough. EVs can store huge amounts of power, a... » read more

Research Bits: Oct. 10


Disposable water-activated battery Researchers at Empa developed a water-activated disposable paper battery that could be used in low-power, single-use disposable electronics such as smart labels for tracking objects, environmental sensors, and medical diagnostic devices. The battery is made of at least one cell measuring one centimeter squared and consisting of three inks printed onto a re... » read more

Authenticating Batteries Before Rapid And Fast Charging


If asked, most consumers will complain about the battery life of their smartphone. In reality, this is more a charging issue since, with traditional charging solutions, even a couple of hours of charging can result in a minimal improvement in charge on some handsets. Smartphone manufacturers are differentiating their offering by providing fast or rapid charging solutions. However, this places t... » read more
