World's first liquid metal battery operates at room temperature

The engineers from the University of Texas have created a new completely unique type of battery. It saves energy, does not have the major disadvantages found in other batteries, and successfully combines many of the advantages of the existing options. Most modern batteries consist of solid electrodes. The new technology involves the use of a liquid metal battery at room temperature. Traditionally, the used batteries have significant energy storage capacity.

But at the same time, the process of accumulating charge is fraught with many problems. Their presence leads to the fact that over time, such batteries become less efficient. Previously developed liquid batteries are capable of transferring energy at a higher level of efficiency, but they also have some disadvantages.

For example, they require significant resources in order to keep the electrodes in a molten state. The battery that was created by a group of scientists, does not need heating and can constantly stay at a temperature not higher 20 degrees. It is the lowest temperature ever used in battery operation. That fact is a major change because modern liquid metal batteries must be stored at temperatures above 240 degrees Celsius.

Yu Ding, one of the authors of the development, believes that the new battery is capable of providing advantages in both solid and liquid state. It has more energy, increased stability and flexibility, and the ability to save energy. The new type of battery contains an alloy of potassium and sodium as an anode and a gallium-based alloy as a cathode.

A battery that operates at the room temperature holds much more energy than modern lithium-ion batteries. Today they are considered as the backbone of almost all electronic devices. But the new type of liquid metal battery is capable of storing more energy.

Its liquid components make it possible to power a variety of devices, from watches to smartphones and other gadgets. In fact, liquid metal has become a kind of promising alternative to replace conventional electrodes. It has demonstrated high energy and power density, that innovative cell can potentially be implemented for smart grid and human-used electronics.
