Electrodes for lithium batteries

A positive electrode for an electrochemical cell including a lithium transition-metal-oxide or lithium-transition metal-oxyfluoride having deposited thereon at least one oxide, oxyhydroxide or hydroxide of zirconium, aluminum, titanium, yttrium, silicon or mixtures thereof, the particles being less than 25 nm in longest dimension, but preferably less than 4 nm. A complete cell as well as a battery incorporating the positive electrode is disclosed as is a method of making the positive electrode, cell and battery.
