Alumina dry-coated cathode material precursors |
abstract |
A microparticulate precursor compound for making an aluminum-doped lithium transition metal (M) -oxide powder that can be used as a cathode active material in a lithium ion battery comprises a transition metal (M) -hydroxide or (M) Coated aluminum oxide coating layer. A higher aluminum doping level can be achieved compared to known prior art techniques by providing an aluminum dry-coating process in which the particulate precursor core compound is mixed with aluminum powder over one or more processes. The crystal structure of alumina is maintained during the coating processes, and the core of each mixed transition metal precursor particle is surrounded by a coating layer containing crystalline alumina nanoparticles. The aluminum concentration in the particulate precursor becomes lower as the size of the core increases. |
