One of the most impressive things about new gadgets packing Retina Displays and quad cores is their great battery life. The difference between the Samsung Galaxy S3 and HTC One X in our battery test was a big factor in making the S3 our top reviewed phone. So when we heard about a method to turn a t-shirt into a battery our ears pricked.
Engineers at the University of South Carolina found a cheap and relatively simple method to imbue everyday t-shirts with charge. You probably won't be able to replicate it, but if you want to try, here's how they did it. They bought a t-shirt and soaked it in a fluoride solution, then baked at a high temperature in an oxygen-free oven.
Once the t-shirt came out of the oven, the fibers were converted from cellulose to activated carbon able to store electrical charge. A quick dousing of a nanometer layer of manganese oxide and you have yourself a totally flexible, super–thin high-performing super capacitor. Now imagine that layered up in your phone the same size as your current battery – goodbye nightly charging.
Presumably the whole thing – when it comes to market – will charge your devices wirelessly, somehow. So now you just need to think up a funky and suitably ironic design – we’re thinking flux capacitor.
