Abstract: The disclosure relates to positive electrode material used for Li-ion batteries, a precursor and process used for preparing such materials, and Li-ion battery using such material in its positive electrode. The disclosure describes a higher density LiCoO2 positive elecdtrode material for lithium secondary batteries, with a specific surface area (BET) below 0.2 m2/g, and a volumetric median particle size (d50) of more than 15 μm. This product has improved specific capacity and rate-capability. Other embodiments of the disclosure are an aggregated Co(OH)2, which is used as a precursor, the electrode mix and the battery manufactured using above-mentioned LiCoO2.
