Abstract
Positive electrode active materials are formed with various metal oxide coatings. Excellent results have been obtained with the coatings on lithium rich metal oxide active materials. Surprisingly improved results are obtained with metal oxide coatings with lower amounts of coating material. High specific capacity results are obtained even at higher discharge rates.
