METAL OXIDE COATED POSITIVE ELECTRODE MATERIALS FOR LITHIUM-BASED BATTERIES
Document Type and Number:
WIPO Patent Application WO/2011/031544
Kind Code:
A3
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.
