Abstract

Process for producing coated mixed lithium oxide particles, in which mixed lithium oxide particles and a mixture comprising aluminium oxide and titanium dioxide are subjected to dry mixing by means of a mixing unit having a specific power of 0.1-1 kW per kg of mixed lithium oxide particles and mixture used, in total, under shearing conditions. Coated mixed lithium oxide particles comprising a mixture of aluminium oxide and titanium dioxide as coating material, wherein the aluminium oxide and the titanium dioxide are in the form of aggregated primary particles and the weight ratio of aluminium oxide to titanium dioxide is 10:90-90:10. Battery cell comprising the coated mixed lithium oxide particles.
