Who would have thought that paper and salt could have made a rechargeable battery? Well, the Swedes did and now they’ve come up with a battery that uses pressed mats of cellulose fibers for electrodes and a salt solution that acts as the electrolyte.

These batteries can be recharged tens of thousands of times, and have a long shelf life. However, they can only deliver one volt as compared to the lithium battery, which can deliver four volts. With these eco-friendly batteries, many developing countries can and will be helped by their cheap, easy construction. Stats for World Bettering Batteries Trending: Older & Chilly
