Image: Alloy in solvent A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional (1D) nanostructures. That could enable the production of thermally stable, strong battery membranes able to withstand temperatures of more than 1,000° C. In “Transformation of bulk alloys to oxide nanowires,” recently published… Read more »

MIT researchers investigate mechanics of sulfide-based solid electrolyte material
IMAGE: Using specialized equipment, a team from MIT did tests in which they used a pyramidal-tipped probe to indent the surface of a piece of the sulfide-based material. Surrounding the resulting indentation (seen at center), cracks were seen forming in the material (indicated by arrows), revealing details of its mechanical properties. Battery scientists are the world are exploring… Read more »
Volvo sells 8 electric buses to Harrogate in the UK
The Harrogate Bus Company of the UK has placed an order for eight Volvo 7900 electric buses. The vehicles will operate in Harrogate, 90 km northeast of Manchester. When the vehicles enter service in 2018, the project will be the first in the UK to use opportunity charging via the common interface OppCharge. The charging stations can also be… Read more »
Could a new supercapacitor technology replace batteries?
Supercapacitors, which feature long cycle life and high power density, are a common topic here at Charged – many foresee them working together with batteries. However, researchers from Augmented Optics in collaboration with the University of Surrey and the University of Bristol, have developed new electrolytes that they believe could be used to create supercapacitors… Read more »
Chroma Systems Solutions invests in the next generation of EV testing products
One major challenge that the EV industry has had to overcome is figuring out how to test its new products. No matter how great and innovative you think your new design is, if you can’t adequately test it, how do you know it’s truly great? Until recently, there were no standard operating procedures for testing… Read more »
Nikola unveils Class 8 hydrogen-electric truck (Updated: Company unveiling video)
Nikola Motor Company, named for a certain Serbian-American inventor, recently unveiled its Nikola One electric semi-truck at its Salt Lake City headquarters. The Nikola One has an electric drivetrain powered by lithium batteries, as well as a hydrogen fuel cell. It has a range of 800-1,200 miles, and delivers over 1,000 hp and 2,000 ft-lbs… Read more »
Faraday Future begins work on US EV manufacturing plant
EV startup Faraday Future has begun construction of a $1-billion, 3-million-square-foot manufacturing plant in North Las Vegas. Industrial construction firm AECOM (NYSE:ACM) is handling the project, and is already engaged in demolition and grading at the site. The facility will include sustainability features such as prismatic skylights for daylighting, roof-mounted solar panels, and energy-efficient heating… Read more »

Engineered Materials Solutions brings a century of clad metal experience to batteries
The methods that automakers use to join Li-ion cells together are almost as diverse as the sizes and shapes of the cells themselves. EV builders are using spot welding, mechanical fasteners, wire bonding and other joining techniques. It’s safe to say that there is no consensus on an ideal solution, and that there’s a lot… Read more »
