    . . .
    Under a three-year, $233,000 grant from the National Science Foundation (NSF), a team led by Dr. George Nelson, an associate professor of mechanical and aerospace engineering at The University of Alabama in Huntsville (UAH), will use X-ray diffraction and multiscale X-ray imaging to study changes in the microstructure of the tin-based anodes –also known as negative electrodes – that affect the battery’s longevity and storage capability.

    "As with most batteries, there is a desire to increase the capacity of sodium ion batteries. Unfortunately, high capacity battery materials like tin expand a lot when fully charged with sodium," says Dr. Nelson.

    "We're using a combination of experiments and numerical models to understand exactly how these changes affect battery performance, so future battery engineers can design the materials and microstructures to make better sodium ion batteries," he says.

    Experiments include electrochemical testing, X-ray diffraction to characterize crystal structure of electrode materials and in operando X-ray tomography. These experimental methods will be coupled with mesoscale computational studies of sodium ion battery electrode microstructures. The research will provide insight into the interactions between microstructure, chemistry and performance in sodium ion batteries.

    Apparently Drs. Christy and Spencer are playing no part:

    idk what he said, but i like it. what is a sodium-ion battery used in?

    I first read about them as one-time, primary batteries that used a thermal reaction to bring them up to operating temperature for things like military rockets and artillery(*). They are a form of "Molten-salt battery."

    * - Primary due to the destruction of the military ordinance leaving nothing to recharge.

    Perhaps worth mentioning this NSF award was made most recently 2018 September. Under current partial US govt shutdown no new awards are being made.

    Or perhaps it's not worth mentioning. But neither was a cheap shot against Christy and Spencer. Bob and I can roll our eyes at each other.

    Of most interest to me, mention of wood anodes. Anything with wood y'know.

    Knowledge of trickery that wizards do (chemistry and such) seems much more satisfying than fantasy writing. In fact you might consider giving it a try yourself.

    Still angry about having a basement full of only silver I see.

    what good is it? i need gold, and lots of it. silver is next to useless, and easily manipulated. ask any lady with a ring

    You will find that some ladies are happy with their silver

    Learning what gives gold that odd color would only make you covet it more I fear. Seventy-nine electrons accompany each nucleus and some of them are moving terribly fast. Relativistically fast, which makes them heavier, which makes their orbitals close to others. Transitions in visible-light ranges thus uniquely happen.

    That is a very loose explanation, but read real authorities on the subject and I'm sure your eyes will fall out. Or some other Harry Pottery thing.

    No other element has electrons with such senses of urgency. Gold's other extreme properties (malleability and ductility) follow from this. Somehow or other.

    Medieval red 'stained' glass was made so by dissolving gold nanoparticles in the melt. Not that glass dudes knew what was going on with overweight electrons. It must have seemed wizardly or Godly. At very least, wholly surprising.

    Sorry about those batteries, Bob. We are just goofing off here.

    For fixed site, weight-be-damned chemical storage of electricity, sodium (or several others) might beat lead/sulfate in dollars. Because what else matters, really?

    UAH folks suggest not lithium, to spare that for transportation where weight does matter and maybe a front-end supply problem exists. Good on them for saying such. It is how grants get funded :)

    ==
    Secondary batteries may have hit a fork in the road. Fixed sites only need KwH/$. Mobile uses need both per $ and per kg. It should not be surprising that different chemistries fit one or the other.

    I love thread drift not that I’ve ever stooped to such practices.

    The UAH grant was mentioned in the local news and I instantly was reminded of two characters including one who claims renewable energy to be a ‘bad thing.’ I also remember a bar conversation by a UAH student who mentioned how important the grants from the two characters were to UAH.

    While I try to not be the spelling police, just can't pass up on this one --

    Are military ordinances published on explosive paper, so that they can be ordnance too?

    Americans can always be trusted to do the right thing, once all other possibilities have been exhausted.​

    He is not the first rascal put in the EPA, other federal agencies, on the bench, or in the White House. I'm content to let the facts and data answer:
