Converting bulk alloys to oxide nanowires could produce cheaper battery membranes

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 »

XL Hybrids upfit powertrains now available to government fleets in all 50 states

XL Hybrids has been selected by the Massachusetts Operational Services Division (OSD) as a vendor for the new Advanced Vehicle Technology statewide contract VEH102. This multi-year contract allows public fleets nationwide to purchase the company’s XL3 Hybrid Electric Drive System as an upfit or retrofit product through an established public contracting mechanism with competitive volume… Read more »

Computational design strategy extends battery life

Batteries are wonderful inventions, but like so many things in life, they don’t last. With every charge and discharge cycle, a battery’s capacity is reduced, until eventually it becomes inadequate for its application. “Why does this degradation occur?” muses Northwestern University’s Christopher Wolverton. “In many cases, something probably happened to the cathode.” Wolverton has developed… Read more »

Conducting polymer increases the energy efficiency of metal-air batteries

A team of researchers affiliated with the South Korean university UNIST has developed a new way to increase the energy efficiency of metal-air batteries by using a conducting polymer. In “Polypyrrole-assisted oxygen electrocatalysis on perovskite oxides,” published in Energy & Environmental Science, Professors Dong-Gyu Lee, Hyun-Kon Song and Guntae Kim explain that, in the cathode… Read more »

Navigant says $3.8 billion worth of advanced batteries shipped in the first 3 quarters of 2016

A new report from Navigant Research examines the current market for advanced batteries (defined as mass-produced products aimed at the automotive or stationary energy storage sectors). In the first three quarters of 2016, Navigant says, over 323 million individual battery cells were shipped, representing 16.1 GWh of energy capacity and $3.8 billion in sales. The… Read more »

NSK demonstrates wheel hub motor with integrated transmission

Japanese automotive supplier NSK has demonstrated what it says is the first transmission-equipped wheel hub motor. In-wheel motors have several advantages – they can reduce the weight of the vehicle, control the drive force of each wheel for improved torque vectoring, and possibly free up room for more passenger and cargo space. However, achieving both… Read more »
