New battery coating could improve smart phones and electric vehicles

The problem with lithium ion batteries made with metal is that during charge cycles they uncontrollably grow dendrites, which are microscopic fibers that look like tree sprouts. The dendrites degrade the performance of the battery and also present a safety issue because they can short circuit the battery and in some cases catch fire.

"You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films," Spriggs said. "We know that these films are on the brink of decomposing to the point where they'll become useless. The data that we're collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They're made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data."

'Answers were off by 30 percent'

From its inception, the project presented a series of hurdles. It took several years to locate the films, and when Spriggs did get his hands on the first few, he didn't have a scanner that could reproduce the optical density on the films. It took about a year to convert a Hollywood-style scanner into one that could provide the level of scientific accuracy required. Then he had to locate the data sheets for the test, because without knowing the camera location, its speed and focal length, he wouldn't be able to analyze the films. Once Spriggs did complete the first scans and roll his sleeves up for the analysis, he discovered that much of the data published were wrong. All the films would need to be reanalyzed.

The Downsizing Uprising | Outside Online

The Downsizing Uprising | Outside Online

In the past five years, thousands of people have been taking simple to an extreme, ditching their three-bedroom homes for micro-abodes of less than 500 square feet. Tiny homes are popping up across the country—sleek glass boxes, log sheds on wheels, converted shipping containers, modern pods built by hand. You can take tiny home building courses online and buy tiny home building plans. There's an annual tiny house conference and even a new online dating network for tiny home dwellers, aka "tiny love mates" (no offense?). Splashy digital slide shows and documentaries like Tiny: A Story about Living Small and Small Is Beautiful glamorize the simplicity of mini-living.

The Downsizing Uprising

The benefits to going small are huge: Tiny homes cost on average $23,000 to build, easing the financial burden of a big mortgage. Downsizing eliminates clutter and limits spending and consumption. In some cases, smaller houses allow you to live off the grid, in remote locations, closer to trails and back country access. And when your house isn't much bigger than a storage shed, you'll naturally spend more time outside, like Laura LaVoie, whose al fresco kitchen in her 120-square-foot North Carolina home—a wooden bar-top with cookware stored below in plastic tubs—isn't much different from our camping kitchen. Not having to mow the lawn or spend your Saturday vacuuming 2,500 square feet means more time for travel and adventure.
