According to an article published in Advanced Energy Materials by researchers at the DOE’s Oak Ridge National Laboratory (ORNL), cobalt is currently the most expensive cathode material used in lithium-ion batteries. The DOE says cobalt accounts for about a quarter of the cost of a typical battery, and was the most expensive cathode material in… Read more »

Indium to launch new adhesive for power module assembly
Indium Corporation, a designer and manufacturer of materials for electronics assembly, plans to release a new adhesive for power module assembly at PCIM Europe, which is scheduled for May 10 to 12 in Nuremberg, Germany. InTACK is a halogen-free adhesive designed to hold a die, chip or solder preform in place during the placement process… Read more »
Researchers develop method for stabilizing interfaces in solid-state batteries
Researchers at MIT and the DOE’s Brookhaven National Laboratory have developed a method for stabilizing the interfaces between the electrolyte and cathodes in solid-state batteries during the sintering process. Based on research reported in Advanced Energy Materials, the team found that when temperatures are above a few hundred degrees Celsius, carbon dioxide and reactions unfold… Read more »
Why is Tesla no longer including mobile charging cables with its vehicles?
First-time EV buyers are famously nervous about charging, which is one reason that most new EVs come with a portable charging cable—it’s reassuring to know that you can plug your new car in as soon as you take it home, without having to deal with charger installation right away. Some drivers find the portable adequate… Read more »
How to test the functionality and safety of EV charging stations, easily and reliably
Sponsored by Fluke Easy EVSE safety testing and troubleshooting with the Fluke FEV100 Test the safety and performance of type 1, level 1 or level 2 electric vehicle ac charging stations (EVSEs) with the Fluke FEV100. This test adapter simulates the presence of an electric vehicle, allowing you to conduct tests in combination with appropriate… Read more »
Are solid-state batteries always safer than Li-ion?
Many in the EV industry see solid-state batteries as the future, and one of the reasons is that the more stable solid electrolyte is expected to be safer than current liquid electrolytes. However, new research indicates that the picture may be more complex. A recent study led by the DOE’s Sandia National Laboratories, published in… Read more »
Do EV brakes and tires cause more particulate pollution?
Huge amounts of misinformation about EVs are churned out each day—and some of this has been coming from the UK’s top environmental official. Environment Secretary George Eustice, who said last November that he doesn’t own an EV or a heat pump, because “the technology is not quite there yet,” recently told members of a parliamentary… Read more »
2022 GMC Hummer EV Edition 1 first drive: five tons of fun
The rebooted electric Hummer is an absurd vehicle, in some ways, but it’s an extremely well-executed absurdity. How do you review a 5-ton electric truck that accelerates from 0 to 60 mph in about 3 seconds? No other vehicle on the market is even close to direct competition. And comparing it to mass-market EVs like… Read more »
Argonne collaborates with NUMiX Materials on battery recycling and biofuel research
Researchers at the DOE’s Argonne National Laboratory have collaborated with sorbent development company NUMiX Materials to investigate the use of a process called capacitive deionization to recycle automotive batteries and produce biofuel. Capacitive deionization separates nickel, manganese and cobalt from other battery materials by relying on their electrical charges. According to Argonne Environmental Engineer Lauren… Read more »
Measuring Electrical Power In Confined Vehicle Space
Whether early or late in the xEV development cycle, installing in-vehicle instrumentation for the accurate measurement of electrical power has been a challenge, until now. Accurate competitive vehicle analyses or production validation requires accessing cables’ inner conductors or busbars inside high-voltage components. CSM’s measurement technology has advanced to include new variants of it’s very successful… Read more »
