Abstract
An electrode material includes a lithium active material composition. The lithium active material composition includes lithium and an active anode material. The lithium active material composition is coated with a lithium ion conducting passivating material, such that the electrode material is lithiated and pre-passivated. An electrode and a battery are also disclosed. Methods of making an electrode material, electrode and battery that are lithiated and pre-passivated are also disclosed.
