In the basement of Grumman Hall, an x-ray pulse produced by a hot, dense plasma – an ionized gas – lasting only fractions of a microsecond both begins and ends an experiment. Hidden within that...Read more about The Laboratory of Plasma Studies: Uncovering mysteries of high energy density plasma physics
Researchers solve battery voltage fade mystery
A team of researchers has discovered the cause of a performance-reducing “voltage fade” that currently plagues a promising class of battery cathode materials called Lithium-rich NMC (nickel magnesium cobalt) layered oxides.
The team includes Andrej Singer, a Cornell professor of materials science and engineering, who completed the work while at the University of California, San Diego.
The research, featured on the cover of the journal Nature Energy, finds the voltage fade is reversible and could eventually lead to new cathode materials for solid state batteries.
