The Oak Ridge National Laboratory Spallation Neutron Source was used to confirm that coating cathode material (blue) with lithium-free niobium oxide (light green) greatly reduced first-cycle capacity loss and improved long-term capacity.

Niobium, a metal best known for its ability to strengthen steel, may also be the secret ingredient that allows lithium-ion batteries to live up to their full potential.

One problem with the lithium-ion batteries powering electric vehicles, smartphones, laptops, power tools, and thousands of other applications is they lose nearly a fifth of their storage capacity the first time they are charged...
