UPTON, NY--A team of researchers led by chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient ...

Chemists have studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings demonstrated that the valence gradient can ...

This image, created by a scanning electron microscope, shows the dual-gradient cathode particles fabricated by the Argonne team. The U.S. Department of Energy’s (DOE) Argonne National Laboratory has ...

The results obtained from a large number of probe measurements of plasma-beam oscillations and of plasma electron temperatures and concentrations in some low pressure hot cathode inhomogeneous ...
