Imagine a world where all the batteries are made of paper. Various devices can be smaller, and used batteries wouldn’t hurt the environment. Thanks to Stanford researchers, we might be living in such a world soon. These batteries work thanks ink infused with carbon nanotubes and silver nanowires.

The idea is not entirely new, but the possibility of coloring paper with ink and making it a battery is impressive. Thanks to this technology batteries will be 20% lighter, and one of the excellent applications will be in electric cars. For a more detailed explanation, check the video below.
