NANOPARTICLE DOPED PRECURSORS FOR STABLE LITHIUM CATHODE MATERIAL

摘要

A precursor compound of a titanium doped lithium cobalt oxide powder consists of either one or more of a non-sintered agglomerated cobalt oxide, hydroxide and oxy-hydroxide powder having a secondary particle size with a d50 of more than 15 µm; said agglomerated cobalt oxide, hydroxide and oxy-hydroxide powder comprising TiO2 in the form of nanoparticles being homogeneously distributed within said agglomerated powder, with a Ti content of between 0.1 and 0.25 mol%.
