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.
Claims13
A method of making an electrode material, comprising the steps of:
- reacting Li with an active anode material to form a lithium active material composition;
- coating the lithium active material composition with a lithium ion conducting passivating material to provide a lithiated and pre-passivated electrode material.
A method of making an electrode, comprising the steps of:
- reacting Li with an active anode material to form a lithium active material composition;
- coating the lithium active material composition with a lithium ion conducting passivating material to provide an electrode material;
- mixing the electrode material with a binder;
- applying the binder and electrode material to a current collector;
- and,
- curing the binder to adhere the electrode material together and to the current collector to form a lithiated and pre-passivated electrode.
