Recently, a new material combination developed by researchers at Stanford University in the United States has helped to create a rechargeable battery that can efficiently store a large amount of renewable energy generated by wind energy, solar energy, etc. With further development, this technology can be fast, Low cost, delivering energy to the grid at normal ambient temperatures.
This technology is known as mobile battery technology and has long been considered one of the choices for storing intermittent renewable energy. However, to date, liquid types capable of generating current have the following disadvantages: Limited by the energy that can be transferred; Extremely high temperatures are required; highly toxic or very expensive chemicals are required.
Assistant Professor of Materials Science and Engineering at Stanford University and his Ph.D. students decided to try potassium and sodium. They mixed potassium and sodium into liquid metal at room temperature, acting as an electron donor or negative fluid for the battery. Theoretically, with other materials In comparison, this liquid metal has at least 10 times the available energy per gram. The researchers said: 'We still have a lot of work to do. This is a new, affordable mobile battery that can take advantage of the rich materials on Earth. , to make solar and wind energy more efficient use. '
