A lithium deficient cathode active material for lithium-ion batteries is described. More particularly, the lithium deficient cathode active material can have multiphase structures, including both a layered or hexagonal structure (e.g., having an R-3m space group) and a spinel structure (e.g., having a Fd-3m space group). Batteries including the cathode active material and methods of preparing the cathode active material are also described. |
