“We’ve transformed the reactivity of iron metal, the cheapest metal commodity,” co-lead researcher from Oregon State University, Xiulei ‘David’ Ji, said in a media statement. “Our electrode can offer athan the state-of-the-art cathode materials in electric vehicles.
In a lithium-ion battery, as its name suggests, a charge is carried via lithium ions as they move through the electrolyte from the anode “We’ve demonstrated that the materials designed with anions can break the ceiling of energy density for batteries that are more sustainable and cost less,” Ji said. “We’re not using some more expensive salt in conjunction with iron – just those the battery industry has been using and then iron powder. To put this new cathode in applications, one needs to change nothing else – no new anodes, no new production lines, no new design of the battery.

Researchers track secret Russian missile launchers in Ukraine using public satellite dataIn the occupied far east of Ukraine, Russian forces are aiming waves of missiles against Ukrainian civilian targets. Each of Russia's state-of-the-art missile launch systems costs more than US$100 million (A$150 million). They allow Russia to launch attacks from safe positions many kilometers behind the front lines.
