Abstract
An anode for an energy storage device may include a current collector. An anode may include a first lithium storage layer overlaying the current collector. An anode may include a first intermediate layer overlaying at least a portion of the first lithium storage layer. An anode may include a second lithium storage layer overlaying the first intermediate layer. The first lithium storage layer may be a continuous porous lithium storage layer including a total content of silicon, germanium, or a combination thereof, of at least 40 atomic %. The first intermediate layer may include a first sublayer in contact with an underlying lithium storage layer and a second sublayer overlaying the first sublayer and in contact with an overlying lithium storage layer, the first sublayer having different a chemical composition than the second sublayer.
