In order to find other solutions for lithium-ion batteries that move away from a dependency on cobalt, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have participated in a collaborative study to identify new potential materials for the positive terminal of a battery, called a cathode. In a battery, lithium ions are inserted into a cathode during charging and released during discharging, providing electricity.

In the new study, a research team led by the University of California, Irvine created and analyzed a material for a lithium-ion cathode that uses no cobalt and is instead rich in nickel. This cathode chemistry is compositionally complex, meaning that it contains small amounts of a wide range of other metals. These metals include molybdenum, niobium and titanium.
