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.

These lithium-ion batteries feature a hybrid solid-liquid electrolyte system, in which the electrodes are coated with a solid electrolyte layer. The incorporation of this technology into Forge Nano’s offering will lead to a substantial reduction in cost per unit energy of lithium-ion batteries. King, Lamuel A.

In … solid-state LIBs [lithium-ion batteries], one important component that needs to be improved to make it more suitable for high performance applications is the electrolyte material. Such solid composite electrolytes also have been previously shown to reduce lithium dendrite formation and proliferation in lithium metal batteries.
