Abstract
Stabilization coating that are uniform and penetrating have been found to provide desirable stabilization coatings for lithium rich metal oxide cathode active materials. In particular, the uniform and penetrating coatings can be particularly desirable for improving storage stability of batteries formed with the active material. The stabilization coatings can be inert metal oxides, such as aluminum oxide. The uniform and penetrating stabilization coatings can be formed using atomic layer deposition. The coatings can further effectively stabilize cycling of the batteries, and batteries formed with the stabilization coating can exhibit modest increases in DC electrical resistance.
