Batteries, which do not heat up, are being developed by the scientists of the Brookhaven National Laboratory at the Department of Energy, USA. Superconductors are the main source of energy efficiency. These stunning materials allow the electric current to flow freely without resistance. However, this usually occurs only at temperatures within a few degrees of absolute zero (minus 459 degrees Fahrenheit), which makes it difficult to deploy today. However, scientists can use superconductivity forces at room temperature. They can transform how energy is generated, stored, distributed and used around the world.
