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 LiCoO 2 positive electrode material for lithium secondary batteries, with a specific surface area (BET) below 0.2 m 2 /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 LiCoO 2 . |
