Researchers solve battery voltage fade mystery

What's causing voltage fade in promising class of battery materials?

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.
