1mm-thick solid-state batteries beat all performance benchmarks

Presented at IEDM 2019 in a paper titled “Millimeter Scale Thin-Film Batteries for Integrated High-Energy-Density Storage”, the new design boasts an areal energy density of 890 μAh.cm -2, the highest reported so far for such devices, according to the authors. The new TFB architecture also exhibits high power density, reaching capacity as high as 450 μAh.cm -2 under 3mA.cm -2 current density. “Thin-film batteries provide some of the highest energy densities of electrochemical energy storage devices, but the inability to increase the electrodes’ thicknesses and control the geometry on the micrometer scale has thus far hindered their effective areal energy density and integration in miniaturized devices”, explained the authors. The team’s solution to these challenges is a high-energy-density, millimeter-scale, thin-film battery integrating a 20μm-thick LiCoO 2 cathode in a Li-free anode configuration, built on silicon wafers using UV photolithography and etching for the successive deposition and patterning of each layer. Because it is built using a wafer-level process, the new battery could be tightly integrated with other electronic devices such as implantables, cut...

US stocks fall; S&P 500 ends with 2nd straight weekly loss

Wall Street capped a choppy week with a second straight weekly loss for the S&P 500 Friday as worries about a potential escalation in the trade war between the U.S. and China erased early gains. Technology companies led the broad slide as investors weighed a report saying the Trump administration is considering ways to limit U.S. investments in China. Bloomberg cited unnamed people familiar with the administration’s internal discussions. Uncertainty over the long-running trade war has fueled volatility in the market and stoked worries that the impact of tariffs and other tactics employed by the countries against each other is hampering U.S. economic and corporate profit growth. The possibility that the U.S. is weighing another way of applying pressure on China dampened investors’ already cautious optimism that the world’s two biggest economies might make progress as their representatives resume negotiations next month. “Here we are, just two weeks out, and now we’re doing things to sort of ruffle feathers again,” said Randy Frederick, vice president of trading & derivatives at Charles Schwab. “That kind of spooked the market.R...

THIS WEEK IN AUTOMATION: Industrial Robots, Angle Sensors and More > ENGINEERING.com

YPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”> ABB Robotics has introduced the IRB 1660ID, its latest compact robot for arc welding and machine tending applications. The IRB 1660ID’s Integrated DressPack design makes it easier to program and simulate predictable cable movements than standard robots with externally routed cables. The decreased cable wear and damage that also results reduce maintenance costs by 50 percent and the compact footprint allows for more efficient robot cell layouts, saving valuable space on the factory floor. To meet the growing demand for superior and even quality in arc welding applications, the IRB 1660ID features a stronger, more rigid upper arm, with a reach of 1.55m and a payload of 6kg. It is able to accommodate heavier weld torches and provides improved wire feeding control near the arc to guarantee high volume production. This, combined with ABB‘s TrueMove technology and the new motion process “Accuracy mode,” provides 0.05mm path repeatability for greater welding results. The Integrated DressPack allows the robot to move at maximum acceleration and s...

CLASS 2A GIRLS: Hatton girls handle Altamont | High School

Hatton’s Kailyn Quails (11) shoots as Altamont’s Tiana Shelton (3) defends during the Northwest Regional semifinals Friday at Wallace State Community College. [DAN BUSEY/DECATUR DAILY] Hatton’s Kailyn Quails (11) shoots as Altamont’s Tiana Shelton (3) defends during the Northwest Regional semifinals Friday at Wallace State Community College. [DAN BUSEY/DECATUR DAILY] Asked if she would have thought her team would win with such numbers, Hatton girls basketball coach Chasta Chamness said “Not really.” Those struggles are not what Hatton expects. What the Hornets do expect, however, is to win, and they beat Altamont 44-36 in Friday’s Class 2A Northwest Regional semifinal. The Hornets (28-5) advanced to play defending state champ Cold Springs on Tuesday for a trip to Birmingham and the state semifinals. “We got into man in the second half, played better defense,” Chamness said. “Rebounded the ball better, finished around the basket, and free throws really helped us today.” That last part is an understatement. Hatton made 23 of 37 free throw attempts. Altamont (17-9) was only 4 for 11. Originally guarded by 5-10 Kalia Todd, Kirk was later guarded by a 5-6 play...

Take a sneak peek at new products featured in the Outdoor Retailer Snow Show

DENVER — More than 9,000 retail buyers will cram into the Outdoor Retailer Snow Show beginning Wednesday morning to see the work of more than 1,000 exhibiting snow-sports equipment, apparel and accessories companies, bringing another huge boost to Denver’s economy at what is otherwise the slowest season of the year for convention and hotel business. But while city tourism and outdoor-recreation leaders will want to talk about the big numbers for show, which runs through Friday, the truth is that every exhibitor at the Colorado Convention Center is a business that is counting on making contacts and making sales at the event. And for the smaller companies that have invested in traveling to Colorado and hoping to stand out even among giants like The North Face or Obermeyer, what happens over the rest of this week can take on that much more importance for their future. Some of those companies, both small and mid-sized showed off their wares a day early at an OR Snow Show media preview to give a sense of what they will be displaying on the floor and how they will be trying to make an impression on buyers who may see dozens of products a day in their search for the next great shoe or...

Best extendable dining table: Choose from glass and wooden styles that are easy to assemble in any space

We all need some extra elbow room now and then, whether that’s at dinner parties and family festivities, or to make space for work, crafts and other table-top activities. Extendable dining tables are the ideal solution for providing that extra space when it’s needed. Once you’re done, they can be reduced in size again to free up space in the room. The most important thing to bear in mind when choosing an extending dining table is your required dimensions. Before you buy, carefully measure your room to work out the size of table you need, accounting for both the extended and non-extended lengths of the table. Interior design is another key factor when choosing a table. If this is going to be one of the first pieces of furniture you buy for your home, bear in mind that the style of your table could set the tone for the whole room. So, no pressure… To help you make your choice, we’ve tried out a range of dining tables – from contemporary designs to traditional and vintage-style options – considering design, build quality and how easy they were to extend. Some extendable tables require assembly at home. We advise checking with the seller before you buy, to ensure you don’t end up t...

EV Charging From Grid Cheaper And Greener Than From A Home Battery

YPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”> Solar & EV owners: don’t stress about charging your car directly from the grid when the sun isn’t shining. The first thing I’ll do in this article is point out it’s difficult to fit caveats into a headline.  The second thing I’ll do now I’m writing the article and have the space to explain is state there are exceptions to the two main points I am about to make, which are: I will cover some exceptions later in the article, but not now.  Maybe in paragraph 46.  The first thing I am going to do is lay down some ground rules on technology and how far into the future I’m going. I’m only looking at the relatively near future, which means I’m going to assume home batteries and electric cars will work much the way they do now without any radical changes in technology. I’ll also assume Australia’s electricity generation will only be around 50% renewable by 2030.  I’m hoping it will be considerably higher, but as I’ve had three failed marriages I have to consider the possibility my optimism levels are slightly above average. I’m confident m...
