Abstract
An anode for an energy storage device such as a lithium-ion energy storage device is disclosed. The anode includes a current collector having a metal oxide layer, a first lithium storage layer overlaying the current collector, a first intermediate layer overlaying at least a portion of the first lithium storage layer, and a second lithium storage layer overlaying the first intermediate layer. The first lithium storage layer is a continuous porous lithium storage layer having a total content of silicon, germanium, or a combination thereof, of at least 40 atomic %.
