Abstract
Cathode materials, batteries, and methods of forming one or more electrodes for batteries are disclosed. A coated cathode material includes a lithium battery cathode material, a first sub-nanoscale lithium metal oxide coating on the lithium transition metal oxide and a sub-nanoscale metal oxide coating on top of the first sub-nanoscale lithium metal oxide coating. The first sub-nanoscale lithium metal oxide and the sub-nanoscale metal oxide coating are each less than 1 nm thick.
