Xenon battery set energy density record
Chemists from the University of Washington found that xenon fluoride (XeF 2 ) - a white crystal that is used for etching in the electronics industry - can rebuild its crystal lattice under a pressure of millions of atmospheres. Under pressure of about 52 GPa, it forms a two-dimensional semiconductor (a, b), and at 70 GPa it forms an absolutely new three-dimensional structure of ferrous metal XeF 8 (s).
It turns out that all the giant energy from a pressure of 70 GPa is converted into chemical energy of molecular bonds. Chong-Shik Wu, a professor of chemistry at Washington University (Choong-Shik Yoo), says this is the most concentrated form of energy storage after nuclear materials.
If you learn to control the release of energy, then theoretically a small cube with such a charge is enough to refuel a car for the entire period of its operation, not to mention less energy-intensive devices.
