thecarchik (1520545) writes "Battery technology is in constant development behind the scenes, though, and the latest to emerge in research at Washington State University promises to be the most powerful non-nuclear energy storage ever. We're used to Nickel-metal hydride (Ni-MH), Lithium-Nickel (Li-Ni) batteries, and Lithium-Iron (Li-Ion) , as you'd find in cars such as the 2011 Nissan Leaf and 2011 Chevrolet Volt. Meet the Xenon difluoride (XeF2) battery, made of a material normally used to etch silicon conductors. Xenon difluoride molecules are usually kept relatively far apart, but to make the battery they are squeezed together at pressures of one million atmospheres --similar to those you'd find half way to the Earth's core--between two diamond anvils."
