Lithium-ion batteries are so ubiquitous that you're probably reading these words on a device that has one installed right now. They're pretty handy. They charge fast and can hold a lot of juice for your laptop or phone, so why wouldn't we just keep using them forever ? Well, they require lithium which has to be mined out of the Earth itself, so that won't last for all eternity. Oh, and they can explode, making them a risk when left next to your bed or in an unmanned part of a plane, so that's not ideal. Luckily, a new breakthrough means we may be able to move on from them.
Enter sodium-ion batteries. As reported by Live Science, a new experiment performed by researchers at the Tokyo University of Science has yielded promising results.
