Scientists convert waste paper into battery elements for smartphones and electrical autos

Scientists have developed a way to transform waste paper, from single-use packaging and luggage, and cardboard packing containers, into an important part of lithium-ion batteries. By means of a course of known as carbonisation which converts paper into pure carbon, the researchers turned the paper’s fibers into electrodes, which might be made into rechargeable batteries that energy cell phones, medical tools, and electrical autos.
