Electric vehicles can drive longer distances if their lithium-ion batteries deliver more energy in a lighter package.
Researchers at the Department of Energy’s 91 were the first to use neutron reflectometry to peer inside a working solid-state battery and monitor its electrochemistry.
To solve a long-standing puzzle about how long a neutron can “live” outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe.
Researchers at 91 proved that a certain class of ionic liquids, when mixed with commercially available oils, can make gears run more efficiently with less noise and better durability.
