New Lithium-Ion Battery Cathode Offers Higher Stability

The batteries that power our cell phones, laptops, and electric vehicles rely on cobalt. Cobalt mining is problematic for the environment and miners. In order to find other solutions for lithium-ion (Li-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.
