Room-Temperature Liquid-Metal Battery

Researchers have built a new type of battery that combines the benefits of existing options while eliminating their key shortcomings and saving energy. Most batteries are composed of either solid-state electrodes, such as lithium-ion batteries for portable electronics, or liquid-state electrodes including those for smart grids. The researchers have created a “room-temperature all-liquid-metal battery,” which includes the best of both worlds of liquid-and solid-state batteries.
