Argonne team develops new approach to cobalt-free Li-ion cathodes

Green Car Congress

Researchers at Argonne National Laboratory have developed a new approach to cobalt-free Li-ion cathodes that avoids some of the problems with other low-cobalt cathode approaches. Ni is in between Co and Mn in all these criteria. Ni, Mn, Co; NMC) oxides with low Mn and Co contents, e.g., NMC-811. Croy, Brandon R.
