This research is studying, how zinc nanowires are affecting the charge capacity of batteries. For instance, zinc nanowires are approximately 15 times thinner than a single human hair! To study this, zinc nanowires were put into these batteries as an electrode alongside with regular zinc, and then these both batteries were recharged for 100 times. Results have shown that the battery with zinc nanowires has a 50 times higher charge capacity, which means that it can store 50 times more energy. Batteries, that are using zinc are eco-friendlier, cheaper, and less dangerous than lithium ion batteries, which we are using in our everyday life. This research could be a start for a whole new, sustainable energy storing industry!
