Everything these days needs a battery. Phones, cars, pacemakers, solar panels. They all need portable electricity storage, but because of the different sizes, shapes and functions, they each need a specially designed battery. What if there was some kind of flexible, modular power storage that could be made to fit any shape?
Enter the paintable battery. Rice University researches have found materials that allow them to spray a battery onto nearly any hard surface, one layer at a time. Apparently you can even paint a battery onto a beer stein. Glad to see that today’s engineering researchers have the right priorities! See Nature.com for more, and hat tip to BB for the find.
