High-nickel-content cathodes have captured the imagination of scientists, as they could enable much higher energy density. However, the high nickel content causes these cathode materials to degrade more quickly, creating cracks and stability issues as the battery cycles. A team of researchers at the DOE’s Brookhaven National Laboratory investigated the valence gradient of cathode materials… Read more »

Knowles develops next-generation safety capacitors to meet the growing demand for 800-volt EV systems
As EV-makers continue to upgrade from 400 V to 800 V systems, parts suppliers have been hustling to keep up with the new specs. Knowles Precision Devices, for example, specializes in high-voltage capacitors—it’s a market leader in multi-layer ceramic capacitors rated from about 200 V up to 12,000 V. Looking back just 10 or 15… Read more »
StoreDot releases samples of its “five-minute” EV battery
In 2015, Israeli battery developer StoreDot announced plans to enter the EV market with battery cells that it said could enable a 300-mile battery pack to be charged in 5 minutes. Now the company has launched engineering samples of its first-generation batteries that are designed to be manufactured at scale on traditional Li-lion production lines…. Read more »
Hong Kong researchers propose novel cathode design for Li-S batteries
A team led by Professor Zhao Tianshou of the Hong Kong University of Science and Technology has proposed a novel cathode design concept for lithium-sulfur (Li-S) batteries. Li-S batteries are regarded as attractive alternatives to Li-ion batteries. They are known for their high energy density, while their major component, sulfur, is abundant, light, cheap and… Read more »
More conductive copper could increase motor efficiency
Researchers at Pacific Northwest National Laboratory (PNNL) claim to have increased the conductivity of copper wire by about five percent. That may seem like a small amount, but it could make a big difference in motor efficiency. Higher conductivity would also mean that less copper would be needed for the same efficiency, which could reduce… Read more »
Automotive connector strategies and solutions for space saving
Sponsored by TTI and TE Connectivity Automotive manufacturers have been building more electronic content into vehicles with powertrain electrification and increasingly sophisticated driver assist systems accelerating that trend. As a result, many sensor-driven control units with multiple printed circuit boards now have kilometers of new cabling and an exponential number of new connections all of which compete… Read more »
New composite material increases current capacity to rev up EV efficiency and range
Scientists at Oak Ridge National Laboratory (ORNL) have used new techniques to create a composite that they claim increases the current capacity of copper wires, providing a new material that can be scaled for use in ultra-efficient, power-dense EV traction motors. The research is aimed at improving the performance and life of components such as… Read more »
New Li-ion superconductor could lead to safer batteries
Researchers from the Korea Institute of Science and Technology (KIST) claim to have developed a sulfide-based superionic conductor—a material with high ion transport properties corresponding to ion conductivity of 10 to 100 mS/cm at room temperature—that can be used as a high-performance solid electrolyte in all-solid-state batteries. All-solid-state battery technology could solve the safety issues… Read more »
Promising lithium-sulfur active battery material made with low-cost liquid phase process
Scientists at the Toyohashi University of Technology have made an active sulfur material and carbon nanofiber (CNF) composite using a low-cost liquid phase process. Their paper, published in the American Chemical Society’s ACS Applied Energy Materials, claims that all-solid-state lithium-sulfur batteries using a sulfur-CNF composite material show higher discharge capacity and better cycle stability than… Read more »
Samsung researchers describe all-solid-state battery with silver-carbon composite layer
Researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) have published a study on high-performance, long-lasting all-solid-state batteries in the journal Nature Energy. Compared to lithium-ion batteries, which employ volatile liquid electrolytes, all-solid-state batteries use non-volatile solid electrolytes that support greater energy density. However, their lithium metal anodes… Read more »
