Miltec UV announces pilot plant for coating Li-ion battery separators

Miltec UV, a manufacturer of UV curing systems, has announced that a pilot plant is now available for testing its CX400 product on customer’s substrates at the company’s Maryland facility. CX 400 is a high-speed coating and UV curing system specifically designed for applying ceramic coatings on polyolefin separators. It can coat any separator films… Read more »

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 »

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 »

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 »

Huawei develops graphene-assisted high-temperature Li-ion batteries

Researchers at Huawei’s Watt Laboratory have unveiled a graphene-assisted Li-ion battery that can withstand high temperatures and offers a long lifespan. According to the researchers, their new technology allows Li-ion batteries to function at temperatures up to 60˚ C (140˚ F), 10˚ C higher than the current upper limit. The lifespan of the graphene-assisted batteries… Read more »

Nanoscale measurement of lithium metal could lead to suppressing dendrite formation

Lithium metal, which can store more energy than carbon, would seem to be an ideal anode material, except for one serious flaw: dendrites, tiny needle-like branching structures that can grow through the battery, eventually causing a short circuit. Now, a joint team of researchers from Caltech and Carnegie Mellon University has measured the strength of… Read more »

Batteryuniversity has the tools to test the biggest batteries

German firm Batteryuniversity (BU) has introduced new test benches capable of testing the largest EV batteries. BU’s new 120 kilonewton shaker can handle a weight of 800 kg, and can test random profiles, sine sweep, superimposed sine and shock impulses. Frequency can be set between 5 and 2,500 hertz. A large low-pressure chamber (8x3x3 meters)… Read more »
