Abstract
A method of making an anode for an energy storage device such as a lithium-ion energy storage device is disclosed. The method may include depositing a first lithium storage layer over a current collector by a first CVD process. The current collector may include a metal oxide layer, and the first lithium storage layer is deposited onto the metal oxide layer. The method may also include forming a first intermediate layer over at least a portion of the first lithium storage layer. The method may further include depositing a second lithium storage layer over the first intermediate layer by a second CVD process. At least the first lithium storage layer may be a continuous porous lithium storage layer having a total content of silicon, germanium, or a combination thereof, of at least 40 atomic %.
