Stabilizing Li-Rich Layered Cathode Materials Using a LiCoMnO Spinel Nanolayer for Li-Ion Batteries.

Lithium-rich cathodes have excess lithium in the transition metal layer and exhibit an extremely high specific capacity and good energy density. However, they still have some disadvantages. Here, we propose LiCoMnO, a new nanolayer coating material with a spinel structure, to modify the surface of lithium cathode oxide (LiMnNiCoO) with a layered structure.
