MIT is developing the super battery of your dreams

The lithium-ion battery in your phone might look like a solid chunk of energy-producing plastic at first glance, but if you were to bust it open and take a closer look, you'd see there's also some liquid inside. That's because most lithium-ion batteries are composed of multiple parts: two solid electrodes, separated by a polymer membrane infused with a liquid or gel electrolyte. Now, MIT researchers believe they have taken the first steps forward in the development of all-solid-state lithium-ion
